2 answers:

8 0

You have to add, and since the denominators are the same, you can add the numerators. 9/20 plus 3/20 is 12/20. This can be simplified by 4, so you divide the numerator by 4, then, divide the denominator by 4. You will then get 3/5 which is the simplest form.

raketka [301]

$\bf \stackrel{\textit{total hours time}}{2}-\cfrac{1}{3}-\cfrac{1}{4}\impliedby \textit{we'll use an LCD of \underline{12}}
\\\\\\
2-\cfrac{1}{3}-\cfrac{1}{4}\implies \cfrac{(12\cdot 2)~-~(4\cdot 1)~-~(3\cdot 1)}{12}\implies \cfrac{24-4-3}{12}\implies \cfrac{17}{12}
\\\\\\
\textit{12 goes into 17 \underline{1 time} and it has a \underline{remainder} of 5 }\implies 1\frac{5}{12}$

which is one hour and 25 minutes.
