Now, let's get rid of the improper fraction. 6 x 3 = 18 18 + 2 = 20 Your new question is what is twenty thirds minus three fourths: 20/3 - 3/4 The lowest common denominator of thirds and fourths is 12. So, 20/3 x 4/4 = 80/12 3/4 x 3/3 = 9/12 So now we have eighty twelfths minus nine twelfths: 80/12 - 9/12 = 71/12 Simplifying this gives us 5 and 11/12ths.
