Think about the proportion and the cross products for this problem: Shelley sold one customer 5 peanut butter biscuits for $3. She sold another customer 7 beef treats for $4.20.
Because the cross products are equal, which statements are true? Select all that apply.
The ratios are not equivalent.
The ratios are equivalent.
The ratios are not a proportion.
The ratios are a proportion.

When cross products are equal, they will have the same ratio. You can prove this by cross multiplying the fractions:

5|3 = 7|4.20

Cross multiply the two:

21=21

This proves that the ratios are equivalent.

The ratios are equivalent.
