What is the ratio of 2 to 4?
Note that the ratio 2 to 4 is said to be equivalent to the ratio 1 to 2, that is 2:4 = 1:2. Note also that a fraction is a number that stands for “part of something”, so although this ratio can be expressed as a fraction, in this case it does NOT represent “part of something”.
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.
