Answer:
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
