What a ratio is?

A ratio is a statement of how two numbers compare. It is a comparison of the size of one number to the size of another number. All of the lines below are different ways of stating the same ratio.

In this way, how do you figure out ratios?

To find an equal ratio, you can either multiply or divide each term in the ratio by the same number (but not zero). For example, if we divide both terms in the ratio 3:6 by the number three, then we get the equal ratio, 1:2. Do you see that these ratios both represent the same comparison?

How do you solve a ratio?

To use proportions to solve ratio word problems, we need to follow these steps:
  1. Identify the known ratio and the unknown ratio.
  2. Set up the proportion.
  3. Cross-multiply and solve.
  4. Check the answer by plugging the result into the unknown ratio.

How do you work out the ratio of something?

To solve this question, you must first add together the two halves of the ratio i.e. 4+2=6. Then you need to divide the total amount using that number i.e. 600/6 = 100. To work out how much each person gets, you then multiply their share by 100.
