Adding and subtracting fractions

A fraction represents a part of a whole and consists of a numerator (top number) and a denominator (bottom number).

To add fractions with different denominators, find a common denominator, convert the fractions, and then add the numerators.

The least common denominator is the smallest multiple that two or more denominators share.

To subtract fractions, ensure they have a common denominator, then subtract the numerators and keep the denominator the same.

The first step is to find the least common denominator, which is 6 in this case.

The result is $$\frac{1}{6}$$ .

You can simplify $$\frac{10}{8}$$ to $$\frac{5}{4}$$ by dividing both the numerator and denominator by 2.

The sum is $$\frac{2}{3}$$ .

The difference is $$\frac{17}{56}$$ .

Having a common denominator means that two or more fractions share the same denominator, allowing for easy addition or subtraction.
