A unit fraction is any one of the form 1/n where n is a positive integer. It is essential in understanding fractional behavior. A numeric fraction is written and represented like: 5/2, or 2^{2/3}.

For any real numbers a and b, where a ≠ 0

a/a=1

b.1=1

Multiplication property of fractions:

For any two fractions a/b. c/d = (a.c)/(b.d).

Operation on the Numerical Fraction:

- Addition
- Subtraction
- Multiplication
- Division

Example: Simplify 220/88

solution:

Very briefly, resolving the numerator and denominator into products of prime factors gives

220 = 2 x 2 x 5 x 11

and

88 = 2 x 2 x 2 x 11

So, 220/88 = 5/2

220 2

Thus, the simplest form of 220/88 is 5/2.

Simplify (x+2)/(x+4)-(x+1)/(x+4)
