Describe what makes a proportion. Give an example of a proportion.(2 points) please

A proportion is an equation that states that two ratios are equivalent. In other words, it compares two fractions or ratios that have the same value. To identify a proportion, you can often cross-multiply to check if the products of the means and extremes are equal.

For example, the statement \( \frac{1}{2} = \frac{2}{4} \) is a proportion. Here, both fractions represent the same value (0.5), and if you cross-multiply, you get \( 1 \times 4 = 2 \times 2 \), which simplifies to \( 4 = 4 \), confirming that the two ratios are equivalent.

A proportion is a statement that two fractions are equal. It shows that two ratios have the same value.

For example, the fraction \( \frac{1}{2} \) is a proportion with \( \frac{2}{4} \) because both equal 0.5. You can check this by cross-multiplying: \( 1 \times 4 = 4 \) and \( 2 \times 2 = 4 \), so they are equal.
