If 8 liters of paint can cover 100 square meters, how many liters are needed to cover 250 square meters?

If 8 liters of paint can cover 100 square meters, how many liters are needed to cover 250 square meters?

Step 1: Understand that 8 liters of paint covers 100 square meters.
Step 2: Determine how many times 100 square meters fits into 250 square meters by dividing 250 by 100.
Step 3: Calculate 250 divided by 100, which equals 2.5.
Step 4: Multiply the result from Step 3 (2.5) by the amount of paint needed for 100 square meters (8 liters).
Step 5: Calculate 2.5 times 8, which equals 20 liters.
Step 6: Conclude that you need 20 liters of paint to cover 250 square meters.
