# What is a proportion example?

If two ratios are equivalent to each other, then they are said to be in proportion. For example, the ratios 1:2, 2:4, and 3:6 are equivalent ratios.

## Keeping this in mind what is ratio and proportion examples?

A ratio is an ordered pair of numbers a and b, written a / b where b does not equal 0. A proportion is an equation in which two ratios are set equal to each other. For example, if there is 1 boy and 3 girls you could write the ratio as: 1 : 3 (for every one boy there are 3 girls)## In the same manner how do you write a proportion?

A proportion is simply a statement that two ratios are equal. It can be written in two ways: as two equal fractions a/b = c/d; or using a colon, a:b = c:d. The following proportion is read as "twenty is to twenty-five as four is to five."## In the same vein what are examples of proportions in real life?

Common examples include comparing prices per ounce while grocery shopping, calculating the proper amounts for ingredients in recipes and determining how long car trip might take. Other essential ratios include pi and phi (the golden ratio).## Do you have your own answer or clarification?

#### What is the example of direct proportion?

The relationship between days and hours is another example of a direct proportionality: time (hr) = 24 × time (days) . Now we combine the direct proportionality for minutes and hours, with the direct proportionality for hours and days: time (min) = 60 × time (hr) = 60 × ( 24 × time (days) ) .
