**January 24, 2008.**Today in class we had a test on fractions.

It was a mixed test with adding, subtracting,

and multiplying. There was 4 questions and

in this scribe 2 of them our solved.

*Now we are going to solve one of the answers together step by step.*

**7 / 8 x 4 / 5 =**

When we multiply fractions we don't have to find a common denominator, all we have to do is multiply the denominators and the numerators.

8 x 5 = 40

*( denominator 40 )*

7 x 4 = 28

*( numerator 28 )*Now our fraction is....

**28 / 40**, But can we reduce that?

40 and 28 are

*by*

**both divisible****4.**

28 divided by 4 is

**7**

40 divided by 4 is 10.

*OUR FINAL ANSWER IS........*

**7 / 10**

**------------------------------------------------------------------**

Our next question is.....

**2 2 / 3 x 4 1 / 2 =**

Since we have a mixed fractions we have to

convert the fraction in to an improper fraction.

2 2 / 3 =

**8 / 3**

3 x 2 + 2 =

**8**

*Now our new fractions are*8 / 3 x 9 / 2 =4 1 / 2 =

**9 / 2**

2 x 4 = 1 =

**9**

*The next step is multiply the numerators and the denominators.***8 x 9 = 72 3 x 2 = 6**

**72 / 6**

*The next part is to convert the*

*improper fraction into a mixed*

*fraction.*

*Since our denominator goes into the numerator evenly we are left with a whole number, witch is our answer.*

*OUR FINAL ANSWER IS.......***12**
