Question

are these ratios equivalent?
5 elementary school students for every 3 middle school students
20 elementary school students for every 19 middle school students
yes no

Explanation:

Step1: Write the ratios as fractions

The first ratio is $\frac{5}{3}$ (elementary to middle school students), and the second ratio is $\frac{20}{19}$.

Step2: Check if they are equivalent

To check if two fractions are equivalent, we can cross - multiply. For $\frac{5}{3}$ and $\frac{20}{19}$, cross - multiplying gives $5\times19 = 95$ and $3\times20=60$. Since $95
eq60$, the two ratios are not equivalent.

Answer:

no
