Proportions are used to compare two ratios or fractions to see if they are equal.

In a proportion, two ratios are set equal to each other, and you find the missing value by cross-multiplying and dividing.

If you have a proportion like 3/4 = x/12, you can cross-multiply: 3 * 12 = 4 * x, which simplifies to 36 = 4x. To solve for 'x,' divide both sides by 4, giving you x = 9.

Solving proportions is helpful for various real-life situations, like cooking or understanding scale drawings.

It's an essential math skill for solving problems involving rates, ratios, and percentages.
