    Step-by-step explanation:

    Let's set up a proportion. The numbers are in a ratio of 2 to 3, and the smaller number is 18, while the larger number is unknown. We can call it x.

    smaller/larger=smaller/larger

    2/3=18/x

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

    2*x=3*18

    2x=54

    We want to find out what x is. We have to get x isolated. Currently, x is being multiplied by 2. The inverse of multiplication is division. Divide both sides by 2.

    2x/2=54/2

    x=54/2

    x=27

    The larger number is 27.
