In a school choir of 40 pupils there were 16 boys find: the ratio of boys to choiresters
Correction: 16/40 = 2/5.
boys = 16
choir = 40
16:40 ~~> 8:20 ~~> ??
To find the ratio of boys to choir members, we need to determine the number of girls in the choir.
Given that there are 40 pupils in total and 16 of them are boys, we can find the number of girls by subtracting the number of boys from the total number of pupils.
Number of girls = Total number of pupils - Number of boys
Number of girls = 40 - 16 = 24
Therefore, the ratio of boys to choir members is 16:24, or simplified, 2:3.
