51 minus 27 3/7 = 23 4/7
43 minus 27 3/7 = 15 4/7
(27 x 3) - (10 x 3) = 17 x 3 = 51
If 6x - 3 = -51, then x = -8
-h/3 -4 = 13 -h -12 = 39 -h = 39+12 -h = 51 h = -51
The Greatest Common Divisor (GCD) for 51 27 is 3
Well, darling, 17 over 18 minus 2 over 3 is the same as 17 times 3 minus 2 times 18, all over 18 times 3. So, that gives you 51 minus 36 over 54, which simplifies to 15 over 54, or 5 over 18. Math doesn't have to be a drag, honey!
51 = 3 * 17 27 = 3 *3 *3 so,gcd = greatest common divisor which in this case =3
12 - 3 + 42 = 51
- 51 (negative 51))
Well, follow along while I work the math. 24/27 - 7/9 = 24/27 - 21/27 = 3/27 = 1/9
First we need to convert to the same type, giving us 49 over 63 minus 27 over 63, giving us 22 over 63.
8/9 - 3/4 = 32/36 - 27/36 = 5/36
