Answer:
54
Step-by-step explanation:
First, we can discover that 40% of the class are boys
100-60=40
Second, we need to work out what ten per cent of the class is, which we get by dividing 36 by 4:
36÷4=9
9 is equal to ten per cent.
Then, we multiply this by 6 because 10×6=60, which is the percentage of girls in the class.
9×6=54
Therefore, we have 54 girls on the bus
