what is 1 over 10 and 2 over 15 with the same denominator
The lowest common denominator would be 10, so 1/2 would be 5/10 and 1/5 would be 2/10.
First, you have to have a lowest common denominator. Eg: 1/2 - 6/13 The lowest common denominator is 26, because 13 * 2 is 26. You multiply 1/2 by 13, to make the denominator 26, which equals 13/26, then multiply 6/13 by 2 to get 12/26. So the equation with the lowest common denominators now plugged in is: 13/26 - 12/26 Subtract the numerators (13 and 12), so the answer is 1/26.
