Question

Five crates hold 20 pounds of materials. Jen set up this problem to find how many pounds of materials one crate holds:

Answer 1

Answer:

Cross multiply, 5x = 20

Step-by-step explanation:

In Cross multiplication,

$\frac{a}{b}=\frac{c}{d}\implies a\times d=b\times c$

Since, the given problem,

$\frac{5}{20}=\frac{1}{x}$

Thus, by the cross multiplication,

$5\times x= 20\times 1$

$5x=20$

Hence, the statement that best describes the step to solve the problem,

' Cross multiply, 5x = 20 '

Answer 2

After setting up the two ratios as a proportion, cross multiply to find the value of x.

Cross multiply, 5x = 20
