Tim spends about 1/3 of each weekday sleeping in about 7/24 of each weekday in school and you die which fraction of a weekday does Tom spend either sleeping or in school

It's 0.625 converted to a fraction its 5/8 of Tom's day

Remark

You need to convert 1/3 + 7/24 to a common denominator. 24ths seem to be the best denominator to use.

1/3 = 8*1/3*8 = 8 / 24

Now add the two fractions together.

8/24 + 7/24 = 15/24 Both numerator and denominator can be divided by 3

15/3 = 5

25/3 = 8

So your fraction is 5/8 = 0.625
