problem.
Thomas has $24 left. How big is the farm? 400 m2.
How much of the farm is cabbages by
fraction? 3 .

Point out that they are solving for how
3. A farmer plants cabbages in 3 of a 400 m2 farm and cucumbers in much of the farm does NOT have any
10
crops. So, they should calculate how much
the remaining 40% of the farm. How many m2 of the farm does not does have crops and subtract it from the
have any crops? total.
400 (1 3 ) = 400 7 = 280

280 (1 0.4) = 280 0.6 = 168
168m2 of the farm does not have any crops.

The most common error in multi-step problems is forgetting to take the answer from the previous step and
apply it to the future step.
Example: 2.
After 1 of the $75 is gone, only $60 are left. It is important to then take the 60% from the $60, and not from
5
the original $75.
