Question

The ratio of orange to brown candies in a bag of M&M's is 4:1. If there are 45 orange and brown candies in the bag of M&M's altogether, then how many brown candies are there?

Answer 1

The ratio of orange to brown M&M's in the bag is 4:1

This means that every 5 M&M's, 4 will be orange and 1 will be brown

You can express this ratio as follows:

`\text{Orange=}(4)/(5)`
`\text{Brown}=(1)/(5)`

Expressing the ratios as fractions will allow you to calculate the total number of candies of each colour in the bag, just multiply the total number of candies by the determined fractions:

`\text{Orange}=45\cdot(4)/(5)=36`
`\text{Brown}=45\cdot(1)/(5)=9`

There are 36 orange candies and 9 brown candies in the bag.
