How to Subtract Fractions with a Calculator

One of the common challenges in fraction subtraction arises when dealing with different denominators. To subtract fractions with unlike denominators, you first need to find a common denominator. This process, known as finding the least common multiple (LCM), ensures that the fractions have the same denominator, making the subtraction straightforward. For example, to subtract $\frac{1}{3}$ from $\frac{2}{5}$, you would first convert them to equivalent fractions with a common denominator of 15: $\frac{5}{15}$ and $\frac{4}{15}$. Then, you simply subtract the numerators: 

$$\frac{5}{15} - \frac{4}{15} = \frac{1}{15}$$

Subtracting Mixed Fractions

Sometimes, fractions may involve whole numbers, commonly referred to as mixed fractions. To subtract mixed fractions, you first need to convert them to improper fractions, perform the subtraction, and then convert the result back to a mixed fraction if necessary. For instance, to subtract $2\frac{1}{4}$ from $3\frac{3}{4}$, you would convert them to improper fractions: $\frac{9}{4}$ and $\frac{15}{4}$. Then, you subtract: 

$$\frac{15}{4} - \frac{9}{4} = \frac{6}{4} = \frac{3}{2} = 1\frac{1}{2}$$
