Question

Q: The ratio of the numbers of Nick's marbles to Michael's is 3:5. Nick has 36 marbles. If Nick receives

another 9 marbles, what will be the new ratio of the number of Nick's marbles to Michael's?

Answer 1

`(3)/(4)`

Explanation:

`(3)/(5) = (36)/(x)`

3x = 36 x 5

3x = 180

x = 60

Michael has 60 marbles.

Nick recieves 9 more marbles so he has 36 + 9 = 45 marbles

The new ratio will be:

`(45)/(60)` =
`(3)/(4)`
