Question

subtracting fractions works just like adding fractions. in fact, you could even think of subtracting fractions as just adding negative numerator.
\\(\frac{4}{5} - \frac{2}{5} = \frac{4}{5} + \frac{-2}{5} = \frac{4-2}{5}\\)

part c

\\(\frac{5}{12} - \frac{1}{7} = \square\\)

Explanation:

Step1: Find common denominator

The least common denominator of 12 and 7 is $12 \times 7 = 84$.

Step2: Rewrite fractions with LCD

$$\frac{5}{12} = \frac{5 \times 7}{12 \times 7} = \frac{35}{84}, \quad \frac{1}{7} = \frac{1 \times 12}{7 \times 12} = \frac{12}{84}$$

Step3: Subtract numerators

$$\frac{35}{84} - \frac{12}{84} = \frac{35 - 12}{84} = \frac{23}{84}$$

Answer:

23, 84
