Subtracting twenty-four eighths from twenty-four sixths gives an answer of three twenty-fourths.
Five over six multiplied by four over seven is calculated by multiplying the numerators and the denominators. Thus, (5 × 4) / (6 × 7) = 20 / 42. This fraction can be simplified by dividing both the numerator and the denominator by their greatest common divisor, which is 2, resulting in 10 / 21.
