Someone bought LaTeX: 1\frac{3}{4}1 3 4 pounds of ham for $14.50. Someone bought LaTeX: 2\frac{1}{2}2 1 2 pounds of turkey for $26.25. Someone bought LaTeX: \frac{3}{8}3 8 pounds of roast beef for $5.50. 1) Which meat is the least expensive per pound?

Answer 1

The least expensive meat per pound is the ham , which cost per pound = $8.29

Explanation:

1) Which meat is the least expensive per pound?

Someone bought 1 3/4 pounds of ham for $14.50.

1 3/4 = 7/4

If 7/4 pounds of ham = $14.50

1 pound = x

Cross Multiply

x = 1 × $14.50/7/4

x = $14.50 × 4/7

x = $8.2857142857

x = $8.29

Someone bought 2 1/ 2 pounds of turkey for $26.25.

2 1/2 = 5/2

If 5/2 pounds of turkey = $26.25

1 pound of turkey = x

Cross Multiply

x = 1 × $26.25/5/2

x = $26.25 × 2/5

x = $10.5

Someone bought 3 /8 pounds of roast beef for $5.50.

3/8 pounds of roast = $5.50

1 pound of roast = x

Cross Multiply

x = 1 × $5.50/ 3/8

x = $5.50 × 8/3

x = $14.666666667

The least expensive meat per pound is the ham , which cost per pound = $8.29
