Example 1.
Ram walked 1\(\frac { 3 }{ 5 } \) km on Monday, 3 \(\frac { 1 }{ 6 } \) km on Tuesday, and 2 \(\frac { 1 }{ 12 } \) km on Wednesday. Find out the distance he walked in all?
Solution:
Ram walked on monday= 1 \(\frac { 3 }{ 5 } \)
Ram walked on tuesday=3 \(\frac { 1 }{ 6 } \)
Ram walked on wednesday=2 \(\frac { 1 }{ 12 } \)
The distance he walked in all days= 1 \(\frac { 3 }{ 5 } \) + 3\(\frac { 1 }{ 6 } \) + 2 \(\frac { 1 }{ 12 } \)
=\(\frac { 8 }{ 5 } \) +\(\frac { 19 }{ 6 } \) + \(\frac { 25 }{ 12 } \)
=\(\frac {8 × 12 }{ 5 ×12 } \) +\(\frac {19 × 10 }{ 6 ×10 } \) +\(\frac {25 ×5 }{ 12 ×5 } \) ( LCM of 5,6,12 is 60)
= \(\frac { 96 }{ 60 } \)+\(\frac { 190 }{ 60 } \)1 +\(\frac { 125 }{ 60 } \)
=\(\frac { 411 }{ 60 } \)
=\(\frac { 137 }{ 20 } \) =6 \(\frac { 17 }{ 20 } \)
Hence, Ram walked 6 \(\frac { 17 }{ 20 } \) km.
Example 2.
Laxman bought 2 \(\frac { 1 }{ 2 } \) kg wheat, 4\(\frac { 1 }{ 4 } \) of sugar, 10 \(\frac { 1 }{ 2 } \) kg rice. How many kg of items did he buy?
Solution:
Laxman bought wheat= 2 \(\frac { 1 }{ 2 } \) kg
Laxman bought sugar=4 \(\frac { 1 }{ 4 } \) kg
Laxman bought rice=10 \(\frac { 1 }{ 2 } \) kg
Total no. of kg of items Laxman bought = 2 \(\frac { 1 }{ 2 } \) + 4 \(\frac { 1 }{ 4 } \) + 10 \(\frac { 1 }{ 2 } \)
=\(\frac { 5 }{ 2 } \) +\(\frac { 17 }{ 4 } \) +\(\frac { 21 }{ 2 } \)
=\(\frac { 5 ×2}{ 2×2 } \) + \(\frac { 17}{ 4 } \) +\(\frac { 21 ×2 }{ 2×2 } \)
= \(\frac { 10 }{ 4 } \) +\(\frac { 17 }{ 4 } \) + \(\frac { 42 }{ 4 } \)
= \(\frac { 69 }{ 4 } \) =17 \(\frac { 1 }{ 4 } \) .
Therefore, Laxman bought 17 \(\frac { 1 }{ 4 } \) kg of items.
Example 3.
Rajesh donated 19 \(\frac { 1 }{ 2 } \) kg of rice, 25 \(\frac { 1 }{ 4 } \) kg of wheat, and 11 \(\frac { 3 }{ 4 } \) of oil. Find how many kgs of groceries he donated?
Solution:
Rajesh donated rice=19 \(\frac { 1 }{ 2 } \)
Rajesh donated wheat=25 \(\frac { 1 }{ 4 } \)
Rajesh donated oil=11\(\frac { 3}{ 4 } \)
Total no. of kg of groceries Rajesh donated =19 \(\frac { 1 }{ 2 } \)+ 25 \(\frac { 1 }{ 4 } \) + 11 \(\frac { 3 }{ 4 } \)
=\(\frac { 39 }{ 2 } \)+\(\frac { 101 }{ 4 } \)+\(\frac { 47 }{ 4 } \)
= \(\frac { 39 × 2 }{ 2 × 2 } \)+\(\frac { 101 }{ 4 } \)+ \(\frac { 47 }{ 4 } \)
=\(\frac { 78 }{ 4 } \)+\(\frac { 101 }{ 4 } \)+ \(\frac { 47 }{ 4 } \)47/4
=\(\frac { 226 }{ 4 } \)=\(\frac { 113 }{ 2 } \)=56\(\frac {1 }{ 2 } \)
Hence, Rajesh donated 56 \(\frac {1 }{ 2 } \) kgs of groceries.
Example 4.
Giri went on walking 3 \(\frac {1 }{ 2 } \) km, and then cycling by 4 \(\frac {1 }{ 4 } \) km and then he took a lift and traveled 8 \(\frac {3 }{ 8 } \) km. Find out how much distance he traveled?
Solution:
Giri went on walking =3 \(\frac {1 }{ 2 } \) km
Giri went on cycling=4 \(\frac {1 }{ 4 } \) km
Giri took a lift and travelled=8 \(\frac {3}{ 8 } \) km
The total distance he travelled= 3 \(\frac {1 }{ 2 } \)+4 \(\frac {1 }{ 4 } \) + 8 \(\frac {3}{ 8 } \)
=\(\frac {7}{ 2 } \)+\(\frac {9 }{ 4 } \)+\(\frac {67 }{ 8 } \)
=\(\frac {7 × 4 }{ 2 ×4 } \) + \(\frac {9 × 2 }{ 4 × 2} \) + \(\frac {67}{ 8 } \) (LCM of 2,4,8 is 8)
=\(\frac {28}{ 8 } \)+\(\frac {18}{ 8 } \)+ \(\frac {67}{ 8 } \)
=\(\frac {113}{ 8 } \)=14 \(\frac {1}{ 8 } \)
Example 5.
Sameera went to a market and bought mangoes 3 \(\frac {3}{ 4 } \) and her sister bought 4 \(\frac {5}{ 8 } \) mangoes. Find how many kgs of mangoes bought by Sameera and her sister?
Solution:
Sameera bought mangoes= 3 \(\frac {3}{ 4 } \)
Sameera sister bought mangoes=4 \(\frac {5}{ 8 } \)
Total no. of kg of mangoes bought by Sameera and her sister=3 \(\frac {3}{ 4 } \) + 4 \(\frac {5}{ 8 } \)
= \(\frac {15}{ 4 } \) + \(\frac {29}{ 8 } \)
= \(\frac {15 × 2}{ 4× 2} \)+\(\frac {29}{ 8 } \)
= \(\frac {30}{ 8 } \)+\(\frac {29}{ 8 } \)=\(\frac {59}{ 8 } \)
=7\(\frac {3}{ 8 } \)
Therefore, Sameera and her sister bought 7\(\frac {3}{ 8 } \) kg of mangoes.
Example 6.
For a birthday party, Akhil distributed 14 \(\frac {1}{ 2 } \) liters of Pepsi, 10 \(\frac {3}{ 4 } \) liters of sprite, and 12 \(\frac {5}{ 8 } \) liters of thum sup. Find how many liters of cool drinks he distributed at the birthday party?
Solution:
Akhil distributed pepsi= 14 \(\frac {1}{ 2 } \)
Akhil distributed sprite=10 \(\frac {3}{ 4 } \)
Akhil distributed thums up=12 \(\frac {5}{ 8 } \)
Total no. of liters of cool drinks Akhil distributed in the party=14 \(\frac {1}{ 2 } \) +10 \(\frac {3}{ 4 } \) +12 \(\frac {5}{ 8 } \)
=\(\frac {29}{ 2 } \)+\(\frac {43}{ 4 } \)+\(\frac {101}{ 8 } \)
=\(\frac {29 ×4}{ 2 ×4 } \)+\(\frac {43 ×2}{ 4 ×2 } \)+\(\frac {101}{ 8 } \)
=\(\frac {116}{ 8 } \)+ \(\frac {86}{ 8 } \)+\(\frac {101}{ 8 } \)
=\(\frac {303}{ 8 } \)=37 \(\frac {7}{ 8 } \)
Akhil distributed 37 \(\frac {7}{ 8 } \) liters of cool drinks at the birthday party.
Example 7.
In a competition between two friends, Anjana prepared 20 \(\frac {1}{ 2 } \) lit of orange juice and Sanjana prepared 22 \(\frac {5}{ 8 } \) of orange juice. Find how many liters of juice are prepared by both of them?
Solution:
Anjana prepared orange juice= 20 \(\frac {1}{ 2 } \)
Sanjana prepared orange juice=22 \(\frac {5}{ 8} \)
No. of liters of juice prepared by both of them= 20 \(\frac {1}{ 2 } \) + 22 \(\frac {5}{ 8 } \)
= \(\frac {41}{ 2 } \)+ \(\frac {181}{ 8 } \)
=\(\frac {41 ×4}{ 2 ×4 } \) +\(\frac {181}{ 8 } \)
=\(\frac {164}{ 8 } \)+\(\frac {181}{ 8 } \)=\(\frac {345}{ 8 } \)
=43\(\frac {1}{ 8 } \)
Anjana and sanjana both prepared 43 \(\frac {1}{ 8 } \) liters of juice.
Example 8.
Sriram has wires of length 6 \(\frac {3}{ 4 } \) m, 10 \(\frac {5}{ 8 } \). Find the length of both the wires?
Solution:
First wire length= 6 \(\frac {3}{ 4 } \)
Second wire length=10 \(\frac {5}{ 8 } \)
Length of both the wires= 6 \(\frac {3}{ 4 } \) +10 \(\frac {5}{ 8 } \)
=\(\frac {27}{ 4 } \) +\(\frac {85}{ 8 } \)
= \(\frac {27 × 2}{ 4 × 2 } \) +\(\frac {85}{ 8 } \)
=\(\frac {54}{ 8 } \) +\(\frac {85}{ 8 } \) =\(\frac {139}{ 8 } \)
=17 \(\frac {3}{ 8 } \)
The length of both wires is 17 \(\frac {3}{ 8 } \) .
Example 9.
Bhaskar spent 8 \(\frac {1}{ 2 } \) hours on work, 2 \(\frac {1}{ 2} \) hours on the playground. He spent 1 \(\frac {3}{ 4 } \)on walking. Find how much time he spent on the day?
Solution:
Bhaskar spent on work=8 \(\frac {1}{ 2 } \)
Bhaskar spent on playground=2 \(\frac {1}{ 2 } \)
Bhaskar spent on walking=1 \(\frac {3}{ 4} \)
Bhaskar spent on the day= 8 \(\frac {1}{ 2 } \) + 2 \(\frac {1}{ 2 } \) + 1\(\frac {3}{ 4 } \)
= \(\frac {17}{ 2 } \) +\(\frac {5}{ 2 } \) +\(\frac {7}{ 4 } \)
= \(\frac {17 × 2}{ 2 ×2 } \) + \(\frac { 5× 2}{ 2 ×2 } \) +\(\frac {7}{ 4 } \)
=\(\frac {34}{ 4 } \) + \(\frac {10}{ 4 } \) +\(\frac {7}{ 4 } \)
=\(\frac {51}{ 4 } \) =12 \(\frac {3}{ 4 } \)
Therefore, Bhaskar spent 12 \(\frac {3}{ 4 } \) hours a day.
Example 10.

Solution:
Srikrishna bought vegetables= 5 \(\frac {1}{ 4 } \) kg
Srikrishna bought groceries=20 \(\frac {3}{ 4 } \) kg
Srikrishna bought chicken= 1 \(\frac {1}{ 2 } \) kg
Srikrishna bought all=5 \(\frac {1}{ 4 } \) +20 \(\frac {3}{ 4 } \) +1 \(\frac {1}{ 2 } \)
= \(\frac {21}{ 4 } \) +\(\frac {83}{ 4 } \) +\(\frac {3}{ 2 } \)
=\(\frac {21}{ 4 } \) +\(\frac {83}{ 4 } \)+ \(\frac {3 ×2}{ 2 × 2 } \)
=\(\frac {21}{ 4 } \) +\(\frac {83}{ 4 } \) + \(\frac {6}{ 4 } \)
=\(\frac {110}{ 4 } \)=\(\frac {55}{ 2 } \)=27 \(\frac {1}{ 2 } \)
Srikrishna bought 27 \(\frac {1}{ 2 } \) kg.
