Coach said I needed to run 7/12 of the track to meet my goal. I already ran 2/4 of the track. How much more of the track do I need to run? to meet my goal?
In order to know how much more of the track I need to run, I have to subtract 7/12 and 2/4. First change the problem to an addition problem. Change 2/4 to a negative number . You should get: 7/12+-2/4
I have to find a common denominator for 7/12 and 2/4. The CD is 12. 4 can go into 12, 3 times. So multiply 2 by 3= 6 . Your new fraction is 6/12. Now since 6/12 is negative we have to see which fraction is largest. 7/12 is larger than 6/12 so the answer will be positive. 7/12-6/12= 1/12. i needed to run 1/12 of the lap to reach my goal! Yay!
