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
unlike denominators: the bottom number of a fraction. to have unlike denominators you must have two fractions with a different number on the bottom of each fraction.
Unlike or dissimilar fraction.

Like fractions have the same denominators (bottom part of fraction), unlike fractions do not.
The simplest way is to convert them to like fractions, or percentages.

Unlike or dissimilar fraction.
Any fraction whose denominator is not 12.

i give up i have been asking this question for 9 years a unlike fraction is where you have two or more fractions and the denominators are all different
3/4 and 5/12
Like fractions have the same denominators (bottom part of fraction), unlike fractions do not.
The answer depends on what he wants to (or needs to) do with it!

In most cases you cannot since the square root is an irrational number, unlike a fraction which is rational.
The definition is a different denominator in a fraction
When adding two or more unlike fractions, yes.
