It depends on the operation required. For example 3/7 and 4/9;
1. Addition - Find the common denominator and simplify.
3/7 + 4/9
Common Denominator is 63 (this is found by multiplying the 7 and the 9)
27/63 + 28/63 = 55/63 -------line 2
2. Subtraction - the same method as addition but instead of adding in line 2, you subtract
3. Multiplication - Simplify by ''canceling'', which is dividing the numerator and denominator of each fraction together.
3/7 * 4/9 = 4/21
4. Division - Invert the second fraction, change the operation to multiplication; and use the same method as multiplication.
3/7 * 9/4 = 27/28
