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

The length of the strip of stamps after 1 stamp has been used can be found by multiplying 217/8 inches by 24/25. 1/25 of the original length is now gone.

(24/25)(217/8) = 5208/200 = 26.04 inches, or 26 1/25 inches.
