8/3 x 2/7 is 16/21
Five multiplied by 3/8 is 1 7/8
21 over 72, or 7 over 24 (simplified)
8
49/64 is.
21/32, which is already in lowest terms
7/8 multiplied by 8 equals 7.
5 plus 3 is 8, multiplied by 7 is 56.
8/7 x 2/7 is 16/49
7 over 40
3/5*7/8*5/3 = 7/8 (3/5*5/3 = 1)
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.
