Subtracting Fractions

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

Subtracting fractions involves finding the difference between two fractions, which requires a common denominator.

A common denominator is a shared multiple of the denominators of two or more fractions, allowing them to be added or subtracted.

To find the LCD, list the multiples of each denominator and identify the smallest multiple they share.

The least common denominator is 20.

First, find the LCD (24), convert the fractions, then subtract to get $$\frac{1}{24}$$ .

The result is $$\frac{2}{3}$$ after finding a common denominator and simplifying.

To simplify a fraction, divide the numerator and denominator by their greatest common factor (GCF).

The result is $$\frac{13}{20}$$ .

Find the LCD (30), convert the fractions, then subtract to get $$\frac{11}{30}$$ .
