There are 3 boys for every 4 girls in mrs smiths class if there are 28 students in the class how many girls and how many boys are there

Boys to girls ratio is 3:4 so for every 7 students 3 are boys and 4 are girls bc 3+4 is total students in the ratio. boys are 3/7 so out of 28 students there are 12 boys and girls are 4/7 so out of 28 students 16 are girls

12/28 are boys

16/28 are girls

Ratio is 3:4

so total is 3+4=7 units

so we know the ratio for every 7 units

count hohw many 7 units there are

28/7=4

4 units

that means 4 times of each seperate unit

3 times 4=12

4 times 4=16

there are 12 boys and 16 girls
