How to fill out fractions ratios and proportions

How to fill out fractions, ratios, and proportions:

Understand the basic concepts:

1. Fractions represent parts of a whole, where the numerator represents the part and the denominator represents the whole.
2. Ratios compare two or more quantities, often written in the form of a:b or a/b.
3. Proportions are equal ratios, where the two ratios are in the same relationship.

Simplify fractions:

1. To simplify a fraction, divide both the numerator and denominator by their greatest common factor.
2. For example, if you have the fraction 6/12, you can simplify it by dividing both numbers by 6 to get 1/2.

Convert fractions to decimals and percentages:

1. To convert a fraction to a decimal, divide the numerator by the denominator.
2. For example, 3/4 would be 3 ÷ 4 = 0.75.
3. To convert a fraction to a percentage, multiply the decimal form by 100 and add a percent sign.
4. Using the same example, 0.75 would be 0.75 * 100 = 75%.

Compare ratios:

1. When comparing ratios, ensure that the units are the same.
2. If the units differ, convert them to a common unit before comparing.
3. For example, if you have the ratios of boys to girls as 3:5 and the ratio of boys to total students as 3:8, convert the second ratio to boys to girls by multiplying both parts by 5 to get 15:40.
