20 * (6 + 1/2) = 20*6 + 20* (1/2) = 120 + 10 = 130 cm
2. Mr. Phillips served 1/2 of a chicken for dinner. 2/3 of the chicken served was eaten. What fraction of the roast served was eaten?
Well.....this could be construed as a" trick " question...if 2/3 of what was served was eaten, then 2/3 must be the answer
However...if we are talking about the fraction of the total roast eaten, we have
(1/2) (2/3) = 2/6 = 1/3 of the whole roast was eaten
3. Mario completed 3/5 of his homework. One fourth of the completed homework was in geography. What franctional part of the homework was in geography?
