Shane: 8 x 3 = 24 Because it is 8h per day for 3 days. Per is like times 24h out of 36 24/36 GCF is 12 divide to and bottom by 12 24 / 12 is 2 36 / 12 is 3 2/3 Shane worked for 2/3 of 36h Percentage: 100% / 3 (because there is 3 parts)= 33.333333333333 33.33333333333 x 2 (because it is there is 2 parts needed) = 66.6666666666% Shane has worked for 66.6666666666% of 36 hours
Andrew: 4 x 6 = 24 Hey did you realise, the 24 is exactly the same! So the fraction would still be 2/3 of 36, and so on, there percentage is still the same, it's still 66.6666666666%
Answer: Both of Andrew and Shane has worked for the exact same time, therefore they have the exact same percentage <span />
Make them have common denominators: -2/8 - 3/8 - 6/8 - 7/8 = Now just do subtraction with numerators: -5/8 - 6/8 -7/8 = -11/8 - 7/8 = -18/8 = Simplify: -9/4 = Make it a mixed fraction: -2 1/4 (D)
