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

5/20 = 1/x

Which of the following best describes how Jen will continue to solve the problem?


Cross multiply, 5x = 20


Cross add, 5 + x = 21


Multiply across, 5 = 20x


Add across, 6 = 20x

Respuesta :

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

Cross multiply, 5x = 20

Answer:

Cross multiply, 5x = 20

Step-by-step explanation:

In Cross multiplication,

[tex]\frac{a}{b}=\frac{c}{d}\implies a\times d=b\times c[/tex]

Since, the given problem,

[tex]\frac{5}{20}=\frac{1}{x}[/tex]

Thus, by the cross multiplication,

[tex]5\times x= 20\times 1[/tex]

[tex]5x=20[/tex]

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

' Cross multiply, 5x = 20 '
