To determine how many pounds of materials one crate holds, let's examine Jen's equation and solve it step-by-step.
The given equation is:
[tex]\[
\frac{5}{20} = \frac{1}{x}
\][/tex]
We need to find the value of [tex]\( x \)[/tex] that satisfies this equation. The problem is simplified by using the method of cross multiplication. Here's how to proceed:
1. Cross multiply to eliminate the fractions:
[tex]\[
5 \cdot x = 20 \cdot 1
\][/tex]
2. Simplify the equation:
[tex]\[
5x = 20
\][/tex]
This step-by-step method shows that Jen will solve the problem by cross multiplying to get the equation [tex]\( 5x = 20 \)[/tex].
Therefore, the correct answer is:
Cross multiply, [tex]\( 5x = 20 \)[/tex].
