Definition of Fractions

In simple terms, fraction is part of a whole. It has two parts: the numerator, or the top number which shows how many parts you have; and the denominator, or the bottom number that tells how many parts a whole is divided into. For instance, the fraction 2/3 means you only have 2 parts of a whole that is divided into 3 equal parts. Solving math fractions may look tricky at first. If you need help with math fractions, particularly with multiplication and division, below are useful tips which can help you solve the problem.

Multiplying Fractions

In multiplying fractions, involves fractions. If there are any mixed numbers in the problem, convert the given into an improper fraction, which means that the numerator is bigger than the denominator. Nonetheless, the following should be done:

1) Multiply the numerators.

2) Multiply the denominators.

3) Simplify the answer if needed. This means factoring both the numerator and the denominator and cancelling out the fraction mixes that have a value of 1.

Dividing Fractions

Following the same procedure in multiplying fractions, convert any mixed numbers into an improper fraction. If you chose to divide the numbers in its mixed form, distributive property will be used which can be more complicated. After which, the following process must be done:

1) Find the reciprocal of the second fraction. For instance, if the given problem is 2/3 ÷ 3/5, convert 3/5 into 5/3. But if you have a whole number, simply put 1 over it.

2) Change the division sign into a multiplication sign. So the problem will look like 2/3 x 5/3.

3) Multiply the numerators.

4) Multiply the denominators.

5) The product should be reduced or simplified if possible. Again, factor out the numerator and denominator until it is already in its simplest form and cancel the fraction mixes that have a value of 1.
