The ratio of boys to girls in a group is 5:3. If there are 22 more boys than girls, work outhor many girls there are.

Girls =33

Boys =55

Total =88

Step-by-step explanation:

Take girls to be x

And boys x+22

5:3

5+3=8

Fraction of girls is ⅜

And boys is ⅝

⅝-⅜=²/8

²/8=22

5/8=?

5/8×22÷2/8=55

²/8=22

3/88=

⅜×22÷²/8=33

7! = 7×6×5×4×3×2

3! = 3× 2

as 7! is multiple of 3! because 7! contains 3! that is 3× 2 as factor

so 7! /(3! ) = 7× 6× 5× 4

= 42 × 20

= 840

7 ft 6 in means 7 1/2, because 6 in is 1/2 of a foot. 7 ft 8 in means 7 2/3 because 8 in is 2/3 of a foot. 23/3 = 7 2/3. 15/2 = 7 1/2.

23/3   *   15/2   = 57 1/2
