Amy had homework for math,science,and history.she spent 1/3 of her time working on math and 1/4 of her time working on science.

Alja [10]

First we need to multiply to make the fractions have equal denominators so we can add/subtract.

math: 1/3 x 4/4=4/12
science: 1/4 x 3/3=3/12

Now we can find the time she spent on history (I assume this is what you are looking for)

Total time-math time<span>-science time=history time</span>
12/12-4/12-3/12
=5/12

Amy spent 5/12 of her time working on history.

1+8 > √65 because √65 is approximately 8.1

8-1 < √65
