RATIOS 1

In a mixed school the number of boys is 95. If there are 165 students, find the ratio of boys to girls.

Solution

Number of girls = Total – number of boys

                          = 165 – 95

                          = 70

Ratio of boys to girls = 95:70

Find the HCF of 95 and 70.

Then we divide both numbers in our ratio by the HCF = 5.

Ratio of boys to girls = 95: 70

                                      5  :  5

                                  = 19:14

Hence the required ratio is 19:14
