_______________________________________________________________

Because in centimeters we measure smaller lengths and for
little larger lengths we measure with meter stick or meter tape
which is quicker,

Explanation:
I want to measure those five items with a
meter stick or meter tape instead of a centimeter ruler
because in centimeters we measure smaller lengths and
for little larger lengths we measure with meter stick or
meter tape as 1 meter = 100 centimeters.

Question 4.
The distance from the cafeteria to the gym is 14 meters.
The distance from the cafeteria to the playground is double
that distance. How many times would you need to use a meter
stick to measure the distance from the cafeteria to the playground?
28 times I would need to use a meter stick to measure the
distance from the cafeteria to the playground,

Explanation:
Given the distance from the cafeteria to the gym is 14 meters.
The distance from the cafeteria to the playground is double
that distance. So number of times would I need to use a meter
stick to measure the distance from the cafeteria to the playground
is 14 + 14 = 28, therefore 28 times I would need to use a meter
stick to measure the distance from the cafeteria to the playground.

Question 4.
Daniel measured the heights of some young trees in the orchard.
He wants to know how many more centimeters are needed to
have a height of 1 meter. Fill in the blanks.
a. 90 cm + __10___ cm = 1 m
10 cm,

Explanation:
Let’s take missing number as x and 1 m = 100 cm,
So 90 cm + x = 100 cm,
x = 100 cm – 90 cm,
x = 10 cm ,
so 10 cm should be added.

b. 80 cm + __20___ cm = 1 m
20 cm,

Explanation
Let’s us take missing number as x and 1 m = 100 cm,
80 cm + x = 100 cm,
x = 100 cm – 80 cm,
x = 20 cm,
so, 20 cm should be added.

c. 85 cm + __15___ cm = 1 m
15 cm,

Explanation:
Let us take missing number as x and 1 m = 100 cm,
85 cm + x = 100 cm,
x = 100 cm – 85 cm,
x = 15 cm,
So, 15 cm should be added.

d. 81 cm + __19___ cm = 1 m
19 cm,

Explanation:
Let us take missing number as x and 1 m = 100 cm,
81 cm + x = 100 cm,
x = 100 cm – 81 cm,
x = 19,
So, 19 cm should be added.
