Answer:

63 cents

Explanation:

Suppose that 13 inches of wire costs 39 cents. At the same rate, how many inches of wire can be bought for 21 cents?​

0.39/13 = 0.03in

o.03 X 21 = 0.63

so 63 cents check

63/21 should equal 39/13

63/21 = 39/13

63 X 13 = 39 X21

21 X 3 X 13 = 3 X 13 X 21

yes

21 X 3 X 13 = 21 X 3 X 13
