Multiply top and bottom of each fraction by 11x12 = 132
(12x9)/132 - (11x5)/132
= 108/132 - 55/132
= (108 - 55)/132
= 53/132
Nothing cancels, so that's the answer.
It's very easy. Just learn the method and you won't need help with fractions any more (-;
(12x9)/132 - (11x5)/132
= 108/132 - 55/132
= (108 - 55)/132
= 53/132

Lowest common demonimator (LCD) is 11*12 = 132
(9*12 - 5*11)/132
= (108 -55)/132
= 53/132
(9*12 - 5*11)/132
= (108 -55)/132
= 53/132

9/11 - 5/12
= (9 x 12)/(11 x 12) - (5 x 11)/(12 x 11)
= 108/132 - 55/132
= 53/132
= (9 x 12)/(11 x 12) - (5 x 11)/(12 x 11)
= 108/132 - 55/132
= 53/132

least common denominator is 12*11= 132
so
108/132 - 55/132 = 53/132
answer
53/132
so
108/132 - 55/132 = 53/132
answer
