Admin What are the steps to solving a proportion?
Solving proportions is simply a matter of stating the ratios as fractions, setting the two fractions equal to each other, cross-multiplying, and solving the resulting equation.

How do you solve proportions with fractions?
Solving proportions is simply a matter of stating the ratios as fractions, setting the two fractions equal to each other, cross-multiplying, and solving the resulting equation.
How do ratios form a proportion?
A proportion is an equality of two ratios. Simply put, whenever we put an equal sign between two ratios and the ratio on the left is equal to the ratio on the right, we say that they form a proportion.
How do you know if a fraction is proportional?
You can tell if two fractions are proportional by using cross multiplication. Only equivalent fractions are proportional. To do this, multiply the denominator, the bottom number in the fraction, of the first fraction with the numerator, the top number in the fraction.
Which ratios form a proportion?
A proportion is made up of two equal ratios. The two ratios that form a proportion must be equal. So, the two ratios must be equivalent fractions. Also, their cross products must be equal.
