A farmer uses 1/3 of his land to grow corn, a quarter of his land to grow lettuce, and 12.5% of his land to grow green beans. He uses the remaining 7 acres to grow wheat. How many total acres does the farmer own?
I'm going to convert 12.5% to a fraction, which is 12 1/2. Find the denominator for 1/3 and 1/2 which is 6. 1/3 x 2 = 2/6 and 1/2 x 3 = 3/6. Add them all together. 12 3/6 + 2/6 + 7 = around 19.8 ~ 20 acres
