### Can you help me on this question?

This answer is correct. 4/12 divided by 2/2= 1/3
The reciprocal of 2/2 is 2/2
Then you multiply straight across and reduce to get 1/3

### How do you find the common denominator

The denominator is that number on the bottom of a fraction, so with 2 different fractions you want to get them in a form where they have the same denominator. Often you will be trying to find the lowest common denominator.

The usual procedure is to multiply one denominator into the top (numerator) of the other fraction. Then repeat this process with the denominator of the second fraction multiplied into the numerator of the first fraction. Then multiply the 2 denominators together and the result is the denominator now of both fractions.

Eg 2/3 and 5/7 become

14/21 and 15/21

Sometimes further simplification is possible where one fraction has a denominator which is a mltiple of the other. eg

2/3 and 5/6

In this case you only need to multiply on the first fraction

4/6 and 5/6

### Find a common denominator for each pair of fractions. Then rename each fraction in the pair

12 has factors 2*2*3
8 has factors 2*2*2
So lowest common denominator is 2*2*2*3 or 24

3/12 = 6/24 and 3/8 = 9/24

### Multiplying mixed fractions

Convert each mixed number (what you call mixed fraction) to an improper fraction, then multiply the two numerators and multiply the two denominators. Reduce the resulting fraction to its simplest form

Example
(2 1/3)*(1 5/7)=?
Convert 2 1/3 to an improper fraction 2 1/3=2+ 1/3 = 6/3+1/3=7/3
Convert 1 5/7 to an improper fraction 1 5/7=1+ 5/7 =7/7 +5/7=12/7
(2 1/3)*(1 5/7)= (7/3)*(12/7)= (7*12)/(3*7)
The 7's in the numerator and denominator cancel one another leaving
12/3=4
(2 1/3)*(1 5/7)=4
Not all products of mixed numbers will give a simple result as this one. More likely they will not.

### If u multiply both terms of 2/3 by 4 you get?

I would not use the word term to refer to the numerator and denominator of a fraction. To get back to your question, if you multiply the numerator and denominator of a fraction by the same number (call it a, with a different from zero) you are in fact multiplying the original fraction by the fraction a/a, and that is equal to 1. So you are just multiplying the fraction by 1.

### How to convert this to fractions 12 1/6 - 2 3/8 -7 2/3 + 19 3/4

One way to solve the problem is to convert all the fractions so that they have the same common denominator, then just add them up.

12 1/6 = 73 / 6 = 292 / 24

2 3/8 = 19 / 8 = 57 / 24

7 2/3 = 23 / 3 = 184 / 24

19 3/4 = 79 / 4 = 474 / 24

Therefore:

(292 / 24) - (57 / 24) - (184 / 24) + (474 / 24) = 525 / 24 = 21 21/24 = 21 7/8

Therefore:

12 1/6 - 2 3/8 -7 2/3 + 19 3/4 = 21 7/8

Good luck, I hope that helps.

### 12(q plus q over 3 plus q over 4 minus q over 6)

OK It is a little difficult trying to figure out the fractions you are trying to describe. Are there 3 fractions within the ( ) ? One with a denominator of 3, one with a denominator of 4, and one with a denominator of 6?

If so, the answer is 9q.

You must change the fractions within the ( ) to a common denominator, which would be 12. That would be 8q+3q-2q all over 12. Since it is all being multiplied by 12 outside the brackets, you just cancel the 12 outside and the 12 denominator inside which leaves the 8q+3q-2q which equals 11q-2q which equals 9q.

Thanks for using Fixya.
