What is 1 over 8 times 8 over 9 and - 3 over 7 times 21 over 25?
Bradsworld1
1/8 x 8/9 = 1/9 : The 8 in the numerator cancels out the 8 in the denominator.
-3/7 x 21/25 = -3 x 3/25 = -9/25 : The 7 in the denominator divides into 21 (3 times).
With multiplication of fractions then the numerators can simply be multiplied together to produce a new numerator and the denominators can also be multiplied together to produce a new denominator. At any stage simplification or cancellation can take place.
