So say you are adding 1/2 and 1 1/2
you would turn the mixed number into a improper fraction by multiplying the denominator by the whole number, then add it to the numerator
for this example it would be 2 x 1 = 2 + 1 = 3 then put it over the denominator
we would get 3/2 then we add 1/2 to it getting 4/2,
then depending on the question we would either leave it as an improper fraction like 4/2 or we would turn it to a mixed fraction, 2 but it will not always be a whole number like this.
like for example if this problem was 1/4 + 1 2/4 we could get 1 3/4
I hope that this helped you somehow because I tried to explain this to the best of my ability.
If he spends 1/4 reading the news, then he spends 3/4 reading the other stuff
3/4 * 8/9 = 24/36 = 2/3 of an hr ...time spent reading sports and comics
(2/3) / 2 =
2/3 * 1/2 = 2/6 reduces to 1/3....so he spends 1/3 of an hour (or 20 minutes) reading the comics
