Hi, I'm Drew Moyer and this is how to do ratios in simplest form in pre-algebra. Writing ratios in simplest form is the same thing as reducing fractions. We want to divide both terms by their greatest common factor. In other words, the biggest number that the two have in common. Let's suppose that a basketball team has won 64 out of 80 games. And we are told to find what is their ratio of wins to losses. Well the wins I'm already given, it's 64 and for the losses, I can get that number just by subtracting 64 from 80 and I find out that they have lost 16 games. So I'd write the ratio like this, 64:16 and then I want to look for a common factor that I can divide out but not just a common factor, I want to find the biggest common factor that they have and it turns out that it's 16. So, I divide both numbers by 16. If I divide 64 by 16 I get 4 and if I divide 16 by 16 I get 1. So, the new ratio is 4 to 1, 4 wins for every 1 loss. I'm Drew Moyer and this is how to do ratios in simplest form in pre-algebra.
