The ratio of the number of boys to the number of girls at a school is 4.5. if there are 120 boys how many students are there altogether

120 boys with a 4:5 ratio, first divide 120 by 4 leaving you with 30, since theres just 1 more girl for every boy, theres 1 more 30 you add, leaving you with 150.

Take your 2 numbers and combine (120+150) leaving you with your answer

270 students total.

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
