4 rows of 5 X’s.
Explanation:
Here, we have constructed an array of 4 rows of 5 X’s and separated the rows with horizontal lines.
b. Draw an array with X’s that has 4 columns of 5. Draw vertical lines to separate the columns. Fill in the blanks.
____ + ____ + ____ + ____= ____
4 rows of 5 = _____
6 columns of 5 = _____
Answer:
4 columns of 5 X’s and the additional equation will be 5 + 5 + 5 + 5 = 20.
Explanation:
Here, we have constructed an array of 4 columns of 5 X’s and separated the rows with vertical lines and the addition equation will be 5 + 5 + 5 + 5 which is 20 and 6 columns of 5 X’s will be 30.
Question 2.
a. Draw an array of X’s with 3 columns of 4.
Answer:
3 columns of 4 X’s.
Explanation:
Here, we have constructed an array of 3 columns of 4 X’s
b. Draw an array of X’s with 3 rows of 4. Fill in the blanks below.
____ + ____ + ____ = ____
3 columns of 4 = _____
3 rows of 4 = _____
Answer:
3 rows of 4 X’s which will be 12 and the additional equation will be 4 + 4 + 4 = 12.
Explanation:
Here, we have constructed an array of 3 columns of 4 X’s and separated the rows with vertical lines and the addition equation will be 4 + 4 + 4 which is 12 and 3 columns of 4 X’s will be 12.
In the following problems, separate the rows or columns with horizontal or vertical lines.
Question 3.
Draw an array of X’s with 3 rows of 3.
____ + ____ + ____ = ____
3 rows of 3 = ____
Answer:
3 rows of 3 X’s which will be 9 and the additional equation will be 3 + 3 + 3 = 9.
Explanation:
Here, we have constructed an array of 3 rows of 3 X’s and separated the rows with horizontal lines and the addition equation will be 3 + 3 + 3 which is 9 and 3 rows of 3 X’s will be 9.
Question 4.
Draw an array of X’s with 2 more rows of 3 than the array in Problem 3. Write a repeated addition equation to find the total number of X’s.
Answer:
5 rows of 3 X’s and the addition equation will be 3 + 3 + 3 + 3 + 3= 15.
Explanation:
As there are 3 rows of 3 X’s and we need to add 2 more rows which will be 5 rows of 3 X’s and the addition equation will be 3 + 3 + 3 + 3 + 3= 15.
Question 5.
Draw an array of X’s with 1 less column than the array in Problem 4. Write a repeated addition equation to find the total number of X’s.
Answer:
2 columns of 5 X’s and the addition equation will be 5 + 5= 10.
Explanation:
As there are 3 columns of 5 X’s and we need to less 1 more column, then there will be 2 columns of 5 X’s and the addition equation will be 5 + 5= 10.
