How do you solve 7 and 1 ninths minus 4 and 2 thirds.?

Answer 1

Here's a step-by-step answer of 7 1/9 - 4 2/3.

1. Find a common denominator, in this case 18 (both 9 and 3 are multiples). Using the new denominator, calculate the new numerators. You now have 7 2/18 - 4 12/18

2. You can't take 12 from 2, so you borrow another set of "18" from the 7. You now have 6 20/18 - 4 12/18

3. Subtract. You now have 2 8/18

4. Reduce your fraction to the lowest mixed number. Your final answer is 2 4/9
