Question

A Nike shoe factory uses 3.5 lbs of leather to make four pairs of shoes.At this rate How many pairs of shoes will 5.25 lbs of leather make?

Answer 1

Answer:

6 pairs

Step-by-step explanation:

It is given

3.5 lbs = 4 pair

We want to know:

5.25 lb = HOW MANY PAIR? (let this be x)

Now, we can write two ratios and equate them, cross multiply and find x(the pair of shoes that can be made with 5.25 pounds of leather). The ratios and algebra is shown below:

$\frac{3.5}{4}=\frac{5.25}{x}\\3.5x=4*5.25\\3.5x=21\\x=\frac{21}{3.5}\\x=6$

Thus,

with 5.25 lbs of leather, 6 pairs can be made
