A proportion is **an equation that equates two ratios**. For example, if there is 1 boy and 3 girls, you could write the ratio like this: 1 : 3 (there are 3 girls for every boy) 1/4 are boys and 3/4 are girls.

**Two ratios are called proportional if the two ratios are equal**. For example, the time it takes a train to travel 50 km per hour is equal to the time it takes to travel the distance of 250 km in 5 hours. For example 50 km/h = 250 km/5 hours

A proportion is **a comparison of two numbers, each representing parts of a whole**. Essentially, a proportion tells you that two fractions are equal, even if the magnitude is different. For example, 1/2 out of 10 marbles is the same ratio as 1/2 out of 50 marbles.

The formula for percentage is **parts/whole = percent/100**. This formula can be used to find the percentage of a given ratio and find the missing value of a part or the whole.

A ratio 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 with a colon, a:b = c:d**. The following ratio is read as “twenty to twenty-five is like four to five.”

1 : **harmonious relation of parts to each other or to the whole** : balance, symmetry. 2a : Fair or equal share, each has done their share of the work. b : rate, percentage. 3 : the relation of one part to another or to the whole in terms of magnitude, quantity, or degree: proportion.

Proportion **tells us something about a proportion or part in relation to a whole**. Children begin to learn about ratio and proportion in 6th grade. For example, they could be shown the following diagram and would need to know that there are 2 green triangles in every 6 triangles (expressed as a fraction, 2/6 of the triangles are green).

Two ratios are equivalent if their corresponding fractions are equivalent. Four sets are said to be proportional **if the ratio of the first set to the second set is equal to the ratio of the third set to the fourth**.

A proportion is **when two fractions or ratios are equal**.

**A ratio is a comparison of two quantities.** **A proportion is an equality of two ratios**. To write a ratio: Determine whether the ratio is part to part or part to whole.
