A jewelry maker purchased 20 inches of gold chain. She used 3 over 8 of the chain for a bracelet. How many inches of gold chain did she have left? ( Inches )

12.5 inches

Step-by-step explanation:

5/8 of 20

= 5 X 20/ 8

= 5 X 10/ 4

= 50/4

= 12 2/4

= 12 1/2 or 12.5

in problems involving proportions, we can use cross products to test whether two ratios are equal and form a proportion. to find the cross products of a proportion, we multiply the outer terms, called the extremes, and the middle terms, called the means.
