Question

Last week, Eva spent seven and three-fifths hours on homework. This week, she spent ten and six-tenths hours. How many more hours did she spend this week?

2

two and three-fifths

3

three and three-fifths

Answer 1

\[10\frac{ 6 }{ 10 }-7\frac{ 3 }{ 5 }\]
Convert to LCD
\[10\frac{ 6 }{ 10 }-7\frac{ 6 }{ 10 }\]
Now since they are both 6/10 they cancel out
\[10-7=3\]
So that is your answer~
