A ratio can be written like this: 15:60, but it can also be written as the fraction 15/60, which can be simplified to 1/4, or 1:4.
We have been given that a zoo has 15 toucans and 60 parrots. We are asked to find the ratio of the number of toucans to the number of parrots at the zoo.
First of all we will represent our given quantities as fraction.
Now we will reduce our fraction to lowest terms.
Since there are 1 toucans for every 4 parrots, therefore, ratio of toucans to parrots is 1:4.
