Question

3/4 of Alvin's marbles are black and 1/5 are green. What would be the ratio of black marbles to the green marbles?

Answer 1

In this question , it is given that

`3/4`of Alvin's marbles are black and
`1/5`are green.

And we have to find the ratio of black marbles to the green marbles.

`(3/4)/(1/5)`

Multiplying both numerator and denominator by 20

`(3*20/4)/(1*20/5)= (15)/(4)`

So the required ratio is 15:4 .
