1. how can you determine if two ratios are equivalent without reducing?

Explanation:

To check if two ratios are equivalent without reducing, use the cross-multiplication method. For two ratios $\frac{a}{b}$ and $\frac{c}{d}$, multiply the numerator of the first ratio by the denominator of the second, and the denominator of the first ratio by the numerator of the second. If the two products are equal, the ratios are equivalent.

Answer:

You can use cross-multiplication: for ratios $\frac{a}{b}$ and $\frac{c}{d}$, verify if $a \times d = b \times c$. If the products are equal, the ratios are equivalent.
