She Is Doing Fractions Who Is Good At Fractions

When I was a kid I also had a problem with fractions. The best advice that I can give you is that you have to address this problem inmediatly. Math is taught in through the years but each class is built on the previous one. Unlike history or other subjects that you can pretty much start from scratch every year, math is based a lot on the foundations. I have met a lot of people that disliked mathematics only because they did not have a good foundation in it (don't we all dislike the things we are not good at?), and it is my believe that if they had a better foundation, they will like it better.
At that level the best you can do is to help her with homework, sit down with her and try to get the concepts to her, help her with the problems (but don't solve them for her- you want to help with homework - not do the homework!).
Good luck

To add or subtract fractions they must have the same denominator. Example 1/3+1/4= ?
The 1st fraction's denominator is 3 and the 2nd's is 4.
So multiply 1/3 *4/4 getting 4/12.
Multiply 1/4 by 3/3 getting 3/12.
Now they have the same denominator and you can just add the numerators together getting (4+3)/12 = 7/12.
To multiply two fractions just multiply the two numerators together and put the result over the denominators multiplird together. Example:
1/4 X 1/3 = 1*1/4*3 = 1/12 {Note * means multiply}
4/5 X 5/4 = 20/20 = 1
To divide two fractions just invert the fraction on the bottom and then multiply. Example:
1/2 divided by 2/3 = 1/2 * 3/2 = 1*3/2*2 = 3/4
4/5 divided by 4/5 = 4/5 *5/4 = 20/20 = 1
A proper fraction is one in which the numerator is larger than the denominator and therefore is less than 1. Examples are: 25/37, 100/807, 1/3, 7/9.
An improper fraction is one which has a numerator larger than the denominator. Examples are:
4/3, 9/2, 501/273, 6/5
A mixed fraction is one that has a whole number plus a proper fraction. Examples are
4 1/2, 3 1/3 50 27/31.
You can convert a mixed fraction to an improper fraction and vice versa.Example:
4 1/2 = (2*4+1)/2 = (8+1)/2 = 9/2. Just take the denominator of the fractional part (2) and multiply it by the whole number (4, add the numerator (1) and place the result over the frational part's denominator (2).
6 2/7 = (7*6+2)/7 = 44/7.
You can convert an improper fractio to a mixed fraction simply by dividing:
9/2 = 4 with remainder 1 so 9/2 = 4 1/2.
44/7 = 6 with remainder 2 so 44/7 = 6 2/7

the question should be phrased as follows:
How can I help my daughter with fractions?
maybe a tutor for a few days or weeks for that particular
subject of fractions?
