Question

In a bag of blue and yellow marbles the ratio of blue marbles to yellow marbles is 3:5 if the bag contains 60 yellow marbles how many blue marbles are there

Answer 1

36 blue marbles

Explanation:

its blue to yellow

3 is blue, 5 is yellow

when you have a ratio you can also say

ex. 3x+5x=y (y in this case is total marbles)

5x=60 then

so x=12

plug it in

3(12)=36

Answer 2

okay man. This is it.

60 yellow marbles.
X blue marbles.

blue:yellow (3:5)



`(60)/(x) = (5)/(3)`
Therefore,


`5x = 180`

`(5x)/(5) = (180)/(5)`

`x = 36`
