📌 Rules

• Converting a ratio to a fraction: To find what fraction of the whole a part represents, add the parts of the ratio together to get the total denominator. For example, if the ratio of flour to sugar is 3:1, the total number of parts is 3 + 1 = 4. Flour is 3/4 of the mix and sugar is 1/4.

• Converting a fraction to a ratio: If 2/5 of the cakes in a bakery are chocolate and the rest are vanilla, the remaining fraction is 3/5 (since 5/5 – 2/5 = 3/5). The ratio of chocolate to vanilla cakes is 2:3.

💡 Tips

• Always simplify to lowest terms: Divide both numbers in a ratio by their highest common factor, or divide the top and bottom of a fraction by the same number. For example, a ratio of 4:6 simplifies to 2:3, and a fraction of 4/10 simplifies to 2/5.

• Quick typing on our platform: Typing your answer is designed to be super quick and simple! Use plain digits with a colon for ratios (like 2:3) or a forward slash for fractions (like 2/5) without adding any spaces or words.

⚠️ Warnings

• Do not use the second part of a ratio as the denominator: If the ratio of boys to girls is 2:3, the fraction of boys is 2/5 (out of the total 5 children), not 2/3!

• Pay attention to what the question asks for: Check whether the answer requires a ratio (using :) or a fraction (using /) and check the exact order of the items mentioned.
