Paula's dog : Carolos' dog = 3 : 1
The total number of ratio units is 3+1 = 4, so each one stands for (48 lb)/4 = 12 lb.
Paula's dog weighs 3·12 lb = 36 lb.
Carlos' dog weighs 1·12 lb = 12 lb.
18/20 is 90%
You can use a calculator to divide 18 and 20 and you will get 0.9 which is 90%
Or. simplify by dividing the top and bottom by 2, to get 9/10 which is still 90%
