Question

In a bag of red and green sweets, the ratio of red sweets to green sweets is 3:4 If the bag contains 12 green sweets, how many red sweets are there?

Answer 1

Given:

The ratio of red sweets to green sweets is 3:4.

Total number of green sweets = 12

To find:

The total number of red sweets.

Solution:

We have,

The ratio of red sweets to green sweets = 3:4.

Let the number of red sweets and green sweets are 3x and 4x respectively.

Total number of green sweets = 12

`4x=12`

Divide both sides by 4.

`x=3`

Now,

Number of red sweets =
`3x`

=
`3(3)`

=
`9`

Therefore, the number of red sweets is 9.
