Maths Subtracting Fractions

To answer this you need to cross multiply. To do this you need to times 7 and 11 together which is 77, then times 12 and 1 which is 12, then you need to take 12 away from 77 which is 65 so thats your numerator. To get your denominator you need to times 12 and 11 which is 132.  So the answer is 65/132!
