Enter the missing numbers in the boxes to complete the table of equivalent ratios. length (in.) width (in.) ? 5 4 ? 6 ? 8 20

We have that,

i.e.

i.e.

Multiplying numerator and denominator by 3, we get,

i.e.

Thus, we get that, the length : width ratio is 2 : 5.

Hence, the complete table is,

Length (in)                 Width (in)

2                                    5

4                                   10

6                                   15

8                                   20

answer: the common difference is -0.10
