7 goes into 19 2 complete times. 7*2=14, but 7*3=21
the true answer is a decimal, one around 2.71
If you have a fraction, take one number and put a different number on top or underneath, for example if you have 2 cats and 3 dogs, the ratio from cats to dogs would be 2:3 but if you did 2 cats to the total number of animals, you would add 2 and 3 and get 5, so the ratio would be 2:5.
You have to collect like terms that means group the numbers that have the same variables
