To identify whether two ratios are equivalent or not, you have to write them down as fractions. If they are equal, then so are the ratios.

A step-by-step guide to finding equivalent rates

Equivalent Rates – Examples 1

Solve this proportion for \(x\) to check if these ratios are equivalent.
\(\frac{3}{4}=\frac{6}{x},x=_\)
Solution:
Use cross multiplication.
\(\frac{3}{4}=\frac{6}{x} ⇒3×x=6×4⇒3x=24\)
\(x=\frac{24}{3}=8\)

Equivalent Rates – Examples 2

Solve this proportion for \(x\) to check if these ratios are equivalent.
\(\frac{5}{10}=\frac{1}{x},x=_\)
Solution:
Use cross multiplication.
\(\frac{5}{10}=\frac{1}{x} ⇒5×x=1×10⇒5x=10\)
\(x=\frac{10}{5}=2\)
