    Answer:

    This is a proportion

    Step-by-step explanation:

    Cross multiply:

    12 * 20 = 16 * 15

    Simplifying:

    12 * 20 = 16 * 15

    Multiply 12 * 20

    240 = 16 * 15

    Multiply 16 * 15

    240 = 240

    Add ‘-240’ to each side of the equation.

    240 + -240 = 240 + -240

    Combine like terms: 240 + -240 = 0

    0 = 240 + -240

    Combine like terms: 240 + -240 = 0

    0 = 0

    Solving

    0 = 0
