Question

24 hops in 30 seconds how many will she make in 50 seconds

Answer 1

Well, first of all, you have to compare. That will be;
30 seconds= 24 hops
50 seconds= y hops
I represented the unknown with y. Anyway, now you have to cross multiply. So y multiplies 30 and 24 multiplies 50. So that will be;
30y= 1200.
Now, you have to divide the both sides by 30. You have to do this because you need to remove everything that is attached to y to find y. Anyway, you have to divide because the relationship between y and 30 is multiplication. And the opposite of multiplication is division. Anyway;
30y/30=1200/30
y= 40. So your answer is 40 hops
Hope i helped. Have a nice day.

Answer 2

Here, lets set up a proportion.

24/30 = x/50

Cross multiply

24*50 = 1200

30*x = 30

1200 = 30x

30x/50 = 1200/30 x= 1200/30

x = 40

Answer: She will make 40 hops in 50 seconds.
