Question

Last winter Armand had 5/6 of a row of stacked logs . At the end of the winter he had 8/15 of the same row left . How much wood did he burn over the winter ?

Answer 1

5/6 - x = 8/15
5/6 - 8/15 = x
25/30 - 16/30 = x
9/30 reduces to 3/10 = x <==Armand burned 3/10 of a row

Answer 2

Answer:

3/10 row

Step-by-step explanation:

First we have to make the fractions even so there denominator have to be equal. So 15 times 2 gets 30 and 6 times 5 gets 30 too. Ok now multiply the nominator by the corresponding number of 25/30 and 16/30. Subtract to get 9/30 now simplify to get 3/10.
