The Rules of Working with Fractions

During the elementary years, one of thing that students should learn about is multiplying fractions. Even if the work at this level is more about dividing, multiplying, subtracting and adding with fraction, it is important in math learning.  Even if working with fraction can be somehow complicated and difficult, it is worth it while creating the math activities that make the learning easy and fun.

When it comes to working with fraction, there are some few rules that someone should keep in mind.

Subtract and add using the same denominators

-        Subtract and add numerators and use one denominator.

Add or subtract fraction using different denominator

-       You can find the common denominator through taking least common multiple for the denominator and through multiplying the denominator.

-       You can convert the fraction by dividing common denominator  and by multiplying the results by  numerator

-       Subtract and add the rule and add the fraction to the same denominator.

Multiply the fraction

-       You can multiply the denominators by the numerators

-       The product of numerators over product of denominators, it will result in the fraction

-       You can simplify resulting fraction when both denominator and numerator are visible  by just one number.

Dividing by the fraction

-       You can multiply the first  numerator by using the fraction of the second denominator for the new numerator

-       You should multiply the second numerator with the fraction numerator for the first denominator of new numerator

-       Multiply the second numerator of faction by using the first fraction denominator and getting the new denominator.

-       When the resulted fraction comes with the numerator which is greater compared to the denominator, you have to divide the numerator by using the denominator so that you may get the mixed number.

Creating of equivalent fraction

-       You should multiply both denominator and numerator using the same number

Convert the mixed number into a faction

-       You should multiply the entire number part using a denominator

-       Add the numerator in order to get  a numerator

-       Use the same denominator as a fraction part of a mixed number 

Convert improper fraction into the mixed number

-       Divide a numerator using a denominator in order to get a part of a whole number

-       The remainder is going to be a numerator to the fractional part

-       The denominator is same as improper fraction denominator

Simplify the fractions

-       You should find greatest common divisor of denominator and numerator

-       You can device both denominator and numerator using greatest common divisor.

If you want to teach your child more about multiplying fractions, you can use available materials to do so.

-       Using the dominoes: you can let the child pick tiles randomly so that she can learn about having different nominators and denominators.  You may also use different cards to teach him about different operations.   You can find more innovative ways to use so that your child can learn more about fraction in a fun way.
