Quizplus · Accepted Answer

Since both fractions have the same denominator, you can subtract the numerators directly: $ \frac{25}{42} - \frac{7}{42} = \frac{25 - 7}{42} = \frac{18}{42} $. Simplifying $ \frac{18}{42} $ by dividing both the numerator and the denominator by their greatest common divisor, 6, gives $ \frac{3}{7} $.
