Question

sadie practiced her spelling words for 3/4 of an hour and max practiced his spelling words for 5/12 of an hour. in simplest firm how muxh longer dud sadie practice than max

Answer 1

We can calculate how much more Sadie practice than Max by substracting the time that Max practice (5/12) from the time that Sadie practiced (3/4):

`(3)/(4)-(5)/(12)=(3)/(4)\cdot(3)/(3)-(5)/(12)=(9)/(12)-(5)/(12)=(9-5)/(12)=(4)/(12)=(1)/((12)/(4))=(1)/(3)`

Answer: Sadie practiced 1/3 of an hour more than Max.
