    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
