To get a number in a ratio, add up the two numbers in the ratio: In this case add up 5 and 8 to get 13 parts. If 52 is split into 13 parts each part is: 52/13 = 4 We then multiply the number of each part by the total for each side of the ratio so: 5 x 4 = 20 8 x 4 = 32 So the answer is 20:32 We can check by adding the ratio up to see if we get our original number, which we do.
