Answer: 5 more boys in class than girls

Step-by-step explanation:

Total number in a class is 35

Ratio of boys to girls is 4:3

Boys =4

Girls =3

Add the two together to give 7

Boys = 4/7×35

Boys =4×5

=20boys

Girls= 3/7×35

Girls =3×5

=15girls

So we have 20boys and 15girls

To know how many more boys than girls

Deduct the number of boys to girls

To give

20-15=5

There are 5more boys in class than girls
