Front

What is the relationship between ratios and fractions?

Back

Ratios can be expressed as fractions. For example, a ratio of 1:2 can be written as the fraction 1/2.

Front

How do you find equivalent ratios?

Front

What is the total number of items when given a ratio and one quantity?

Back

To find the total number of items when given a ratio and one quantity, use the formula: Total = (given quantity / part of ratio) * total parts in ratio.

Front

How do you solve for an unknown in a ratio?

Back

To solve for an unknown in a ratio, set up a proportion and cross-multiply to find the unknown value.

Front

What is a proportion?

Back

A proportion is an equation that states that two ratios are equal. For example, if a/b = c/d, then a, b, c, and d are in proportion.

Front

How do you convert a ratio to a fraction?

Back

To convert a ratio to a fraction, write the first term as the numerator and the second term as the denominator. For example, the ratio 3:4 can be written as the fraction 3/4.
