How do you multiply mixed number? - Answers

Some would suggest you just "Turn it into a decimal"PROBLEM ALERT: Great for 1/4 where 1/4 = 0.25, but what about numbers like 1/3 where the decimal goes on forever 1/3 = 0.333333333333333 --> infinityWhy not follow the old school method?Lets demonstrate with 2 x 3 3/4 x 5 1/3 = ?First change all number to their fractional form 2=2/1 , 3 3/4 = 15/4 , 5 1/3 = 16/3The equation is then 2/1 x 15/4 x 16/3 = ?The top numbers (numerators) multiplied together are (2x15x16) = 480The bottom numbers (denominators) multiplied together are (1x4x3) =12Divide numerator answer by the denominator number to get the answer (240)/(12) = 40The change it to decimals method would give 39.99975 if 1/3 is assumed to be 0.3333The cleanest and easiest way is to change each one to animproper fraction, and then multiply those.
