Ratio Problems Flashcards

A way of comparing two or more quantities, showing the relative sizes of the quantities.

Divide all parts of the ratio by their highest common factor (HCF).

Add the parts of the ratio, divide the total quantity by the sum of the parts, then multiply by each part of the ratio.

Ratios that represent the same relationship, found by multiplying or dividing all parts of the ratio by the same number.

Multiply or divide all parts of the ratio by the same number to scale it up or down.

A ratio where the numbers have no common factors other than 1.

Adjust the quantities of ingredients by scaling the ratio to match the required total amount.

Write each part of the ratio as a fraction of the total (e.g., for 2:3, write 2/5 and 3/5).

A relationship where two ratios are equal, often used to solve problems involving scaling or sharing.

A ratio where one part is reduced to 1 (e.g., 3:6 becomes 1:2).
