Convert Ratio to Fraction Add the ratio terms to get the whole. Use this as the denominator. 1 : 2 => 1 + 2 = 3. Convert the ratio into fractions. Each ratio term becomes a numerator in a fraction. 1 : 2 => 1/3, 2/3. Therefore, in the part-to-part ratio 1 : 2, 1 is 1/3 of the whole and 2 is 2/3 of the whole.
How do you convert a ratio to two numbers?
To calculate the ratio of an amount we divide the amount by the total number of parts in the ratio and then multiply this answer by the original ratio. We want to work out $20 shared in the ratio of 1:3. Step 1 is to work out the total number of parts in the ratio. 1 + 3 = 4, so the ratio 1:3 contains 4 parts in total.
How do you convert simple ratios?
How to Simplify a Ratio A : B when A and B are both whole numbers List the factors of A. List the factors of B. Find the greatest common factor of A and B, GCF(A, B) Divide A and B each by the GCF. Use the whole number results to rewrite the ratio in simplest form.
What is the formula for calculating ratios?
How to calculate a ratio Determine the purpose of the ratio. You should start by identifying what you want your ratio to show. Set up your formula.

How do you solve 3 ratios?
How to Calculate Ratios of 3 Numbers Step 1: Find the total number of parts in the ratio by adding the numbers in the ratio together. Step 2: Find the value of each part in the ratio by dividing the given amount by the total number of parts. Step 3: Multiply the original ratio by the value of each part.
