The ratio of pink rose bushes to white rose bushes in a garden is 12 to 15. There are 48 pink rose bushes in the garden. How many white rose bushes are in the garden?

60 white rose bushes

Step-by-step explanation:

Let's make a proportion using this setup:

pink roses/white roses=pink roses/white roses

There are 12 pink roses for 15 white roses, and 48 pink roses for x (the unknown and what we are trying to find) white roses.

12 pink roses/15 white roses=48 pink roses/x white roses

12/15=48/x

Cross multiply. Multiply the numerator of the first fraction by the denominator of the second. Then, multiply the denominator of the first by the numerator of the second.

12*x=15*48

12x=720

To solve the equation, we want to find out what x is. In order to do this, we have to get x by itself. Perform the opposite of what is being done to the equation. 12 and x are being multiplied. The opposite would be division, so divide both sides by 12.

12x/12=720/12

x=720/12

x=60

There are 60 white rose bushes in the garden
