Answer

524\frac{5}{24}

Step-by-step solution

4 steps
  1. Identify the initial amount of milk and the amount of milk used.

    Grace initially had 78\frac{7}{8} litres of milk.
    She used 23\frac{2}{3} litres of milk.

  2. Subtract the amount of milk used from the initial amount to find the remaining milk.

    To subtract fractions, find a common denominator. The least common multiple (LCM) of 8 and 3 is 24.

  3. Convert the fractions to equivalent fractions with the common denominator.

    For 78\frac{7}{8}:

    78=7×38×3=2124\frac{7}{8} = \frac{7 \times 3}{8 \times 3} = \frac{21}{24}

    For 23\frac{2}{3}:

    23=2×83×8=1624\frac{2}{3} = \frac{2 \times 8}{3 \times 8} = \frac{16}{24}
  4. Perform the subtraction.

    Remaining milk=2124−1624\text{Remaining milk} = \frac{21}{24} - \frac{16}{24} Remaining milk=21−1624\text{Remaining milk} = \frac{21 - 16}{24} Remaining milk=524\text{Remaining milk} = \frac{5}{24}

    The fraction of milk that remained is 524\frac{5}{24}.
