Acarpenter has several boards of equal length. he cuts 3/5 of each board. after cutting the boards, the carpenter notices that he has enough pieces left over to make up the same length as 4 of the original boards. how many boards did the carpenter start with?

To answer his question you will consider that you have 4 whole pieces. If the remaining part is 2/5 (1 - 3/5 = 2/5), that you will need to figure out how many groups of 2/5 it takes to make 4. You get this answer by dividing 4 by 2/5. The answer is 10. You started with 10 pieces.

Sorry can't answer that question

Well in order to lose a pound you would have to burn 1,500 calories. the more calories you burn the more weight you lose. in order to lose 2 pounds you would have to run 4 hours and 28 minutes.
