3 1/3 - 1 3/4 = 3 4/12 - 1 9/12 IE. 4/12 < 9/12 2 + 1 + 1/3 - 1 3/4 = 2 + 12/12 + 4/12 - 1 9/12 = 1 7/12 Please somebody explain these steps. Answer this Question

to combine thirds and fourths, you need a common denominator: 12 1/3 = 4/12 1/4 = 3/12, so 3/4 = 9/12 You can't subtract 49 from 4, so you need to borrow 12/12 from the 3. After that, you just have 2 16/12 - 1 9/12 2-1 = 1 16-9 = 7
