Annabelle arranged her 42 building blocks into 3 rows of 14 blocks. Then, she rearranged them into 6 rows of 7 blocks. What two other factor pairs could Annabelle use to help her rearrange the blocks again? Explain your answer using complete sentences.

Two other factors are 2 rows of 21 blocks and 1 row of 42 blocks.

Given that,

According to the scenario, computation of the given data are as follows,

Total factors for 42 blocks = 3 rows of 14 blocks , 6 rows of 7 blocks, 2 rows of 21 blocks and 1 row of 42 blocks.

As two of them are already used,

Then the other factors Annabelle could use = 2 rows of 21 blocks and 1 row of 42 blocks.

21 rows 2 blocks

1 row 42 blocks

Step-by-step explanation:

Given that:

Number of blocks with Annabelle = 42

First arrangement = 3 rows 14 blocks

Second arrangement = 6 rows 7 blocks

To find:

The other two factor pairs that could be used to rearrange the blocks again?

Solution:

Here, we will have to find the factor pairs of total number of blocks present with Annabelle.

i.e. 42

First of all, let us have a look at the factor pairs of 42.

Therefore, the other two factor pairs can be 2, 21 and 1, 42.

The other two possible factor pairs are:

21 rows 2 blocks

1 row 42 blocks
