Last year at science camp there were 140 people sleeping in cabins. There were 18 students for every 2 chaperones. How many students were sleeping in cabins?

126 students

Step-by-step explanation:

18+2=20

140 divided by 20=7

7x18=126

140-126=14 chaperones

step-by-step explanation:

you divide the denominator by the numerator on both sides and if the quotients are equal then the fractions are equivalent

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

its b) 840✌✌✌
