Question

Vanessa buy a strip of 25 postage stamps. The strip of stamps is 217/8 inches long. How long is a strip after vanessa uses one stamp?

Answer 1

25 postage stamps is 217/8 inches long.

Find the length of 1 postage stamp:

25 postage stamps = 217/8

1 postage stamp = 217/8 ÷ 25

1 postage stamp = 217/8 x 1/25 = 217/200 inches long

Find the length of the postage stamp left:

Left = 25 - 1 = 24 postage stamps

1 postage stamp = 217/200 inches long

24 postage stamps = 217/200 x 24 = 651/25 inches long

Answer: The strip is 651/25 inches long
