Question

There are 72 gold coins and 32 silver coins in a bag. Using the same porportion, if there are 9 gold coins in a bag, how many silver coins will you find?

Answer 1

We will find 4 silver coins in the bag.

Explanation:

Number of gold coins = 72

Number of silver coins = 32

Ratio of gold coins to silver coins =
`(72)/(32)=(9)/(4)`

Ratio of gold coins to silver coins = 9 : 4

If there are 9 golds in bag,then number of silver coin will be x

9 : 4 : : 9 :x

`(4)/(9)=(9)/(x)`

`x=(9* 4)/(9)=4`

We will find 4 silver coins in the bag.
