There are many ways to write numeric fractions.

Improper, proper, and mixed fractions are examples of different way of writing them.

Interpreting fractions are another concern to math learners.

Common mistakes are always made in mathematically operation involving fractions.

Example of math error having fractions:
5 1/3 x 1/2 = ?

Correct answer will be (16 / 3) x (1/2) = 16 / 6

Mistake: 5 x (1/3) x (1/2) = 5 / 6 !

What is the error? ==> Interpretation mistake.

5 1/3 is taken to be 5 x (1/3) ! ==> 5 and 1/3 are taken to be 2 separate numbers !

Actually 5 1/3 is a mixed number with 5 whole and 1/3 piece.

Common error is thinking 5 1/3 as 5 multiply by (1/3).

Learn to interpret fractions properly will solve this unnecessary mistake.

Note:
5 1/3 is converted to improper fraction by changing the numerator. The numerator is changed by having the denominator "3" of the (1/3) multiply to the "5" and adding the "1" of the (1/3).

Summary: 3 x 5 + 1 = 16 at the improper fraction numerator.

Learned how to read fractions? Its right interpretation will serve you good by making less mistakes while doing fractional manipulations.
