Question

Cody has 7/8 pound of cheese. he uses 1/7 since there are 16 ounces in a pound how much is left

Answer 1

Step One
Find the fraction left.
Starting amount = 7/8 pound
Used amount = 1/7 of a pound.

The common denominator of these two fractions is 8 * 7 = 56

Amount left = amount started with - amount used
Amount left = 7/8 - 1/7
Amount left = $\frac{7 *7 }{8 * 7} - \frac{1 * 8}{7 * 8}$
Amount left = $\frac{49 }{56} - \frac{ 8}{56}$
Amount left = 41 / 56 pounds

Step Two
Convert the Answer to ounces.

Ounces = (41/56) * 16 
Ounces = 11.71 ounces  almost 11 3/4
