Question

in a mixed school, there are 110 students if 44 of them are
girls find the ratio of boys and girls​

Answer 1

Answer:

The explanation is much longer than doing the mathematics.

The ratio of 15 boys to 10 girls is equivalent to the ratio of 3:2

Explanation:

Consider the starting point:

We have 3 boys and 2 girls. This gives a total count of 5

So we need to see how many lots of 5 will fit into 25.

5 lots of 5 gives 25

So we have 5 lots of the ratio 3:2
