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?

Respuesta :

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,

[tex]2x+x=18[/tex]

[tex]3x=18[/tex]

Divide both sides by 3.

[tex]x=\dfrac{18}{3}[/tex]

[tex]x=6[/tex]

Now,

Number of tulips [tex]=2(6)[/tex]

                           [tex]=12[/tex]

Therefore, the number of tulips is 12.
