What does it mean for two ratios to be equivalent?

Back

Two ratios are equivalent if they represent the same relationship between quantities. For example, the ratios 1 : 2 and 2 : 4 are equivalent because both simplify to the same fraction, 1/2.

Front

How do you find the total parts in a ratio?

Back

To find the total parts in a ratio, add the numbers in the ratio together. For example, in the ratio 3 : 5, the total parts are 3 + 5 = 8.
