Question

Jethro is planting flowers in his garden. He wants the ratio of tulips to roses to be 2 to 1. Jethro wants to plant a total of 18 flowers. How many tulips should he plant?

Answer 1

Given:

Ratio of tulips to roses = 2:1

Total number of flowers = 18

To find:

The number of tulips.

Solution:

Let the number of tulips and roses are 2x and x respectively.

According to the question,

`2x+x=18`

`3x=18`

Divide both sides by 3.

`x=(18)/(3)`

`x=6`

Now,

Number of tulips
`=2(6)`

`=12`

Therefore, the number of tulips is 12.
