A zoo has 14 monkeys and 18 chimpanzees.
To write the ratio of numbers x and y we use three ways given below
1. x to y
2. x : y
3.

Now write the ratio in three ways comparing 14 monkeys and 18 chimpanzees.
Let x be the number of monkeys
y be the number of chimpanzees
So ratio becomes
14 to 18
14 : 18
