    Step-by-step explanation:

    Let's create a proportion using the following setup:

    persons/rice=persons/rice

    We know that 12 persons can eat 8 kilograms of fried rice.

    12 persons / 8 kg of rice = persons/rice

    We also know that x (unknown) persons can eat 20 kilograms of fried rice.

    12 persons / 8 kg of rice = x persons / 20 kg of rice

    12/8=x/20

    x is being divided by 20. The inverse of division is multiplication. Multiply both sides of the equation by 20.

    20 (12/8) = (x/20) 20

    20*12/8=x

    20*1.5=x

    30=x

    30 persons can eat 20 kilograms of fried rice.
