18/8 = x/3

x = 6.75 inches (length)

Step-by-step explanation:

Hi, to answer this question we have to write 2 ratios using the information given:

A larger rectangle has a length of 18 inches and width of 8 inches.

Inches / width = 18/8

So, for a rectangle that has a length of x inches and width of 3 inches the ratio is:

x/3

Solving for x:

18/8 = x/3

18/8 (3) = x

6.75 in = x
