Her Average Is A 76%. You Would Need To Add The 2 Percentages Together & Come Up With 152%. You Would Then Divide That 152% By 2 (Representing The 2 Previous Percentages). You Would Then End Up With 76% As An Average Percentage

Are these ratios equivalent?
vaieri [72.5K]

Answer:

Yes

Step-by-step explanation:

3 medium cars to 1 small car can be made into a fraction like this: \frac{3}{1} or \frac{1}{3}. But you must be consistent if the denominator represents medium cars or small cars.

For this, I'm just going to make medium cars the numerator.

18 medium cars to 6 cars can be made into a fraction like this : \frac{18}{6}.

When you divide both fractions in a calculator (or in your head), you will realize that they both are the same value (equivalent).

\frac{3}{1}=\frac{18}{6} = 3

\frac{1}{3} = \frac{6}{18} = .3333333

These ratios are equivalent.
