Diana serves 8 kg of fried rice for 12 persons. How many persons can eat 20 kg of

fried rice?

30 people

Step-by-step explanation:

1) Set up a proportion, 8kg/12 = 20kg/x

2) Do cross multiplication to solve for x

3) x = 30 people

30 persons

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.
