7 thirds divided by 2 thirds equals 3 whole groups and 1 fractional part.

what fraction of a group is left over? 1 third/ 2 thirds
I have ________ of a group left over.

1 answer

To find the leftover fraction after dividing \( \frac{7}{3} \) by \( \frac{2}{3} \):

  1. Perform the division: \[ \frac{7}{3} \div \frac{2}{3} = \frac{7}{3} \times \frac{3}{2} = \frac{7 \times 3}{3 \times 2} = \frac{21}{6} = \frac{7}{2} = 3 \frac{1}{2} \]

  2. Interpret the result: From the calculation, \( \frac{7}{2} \) is equal to \( 3 \) whole groups and \( \frac{1}{2} \).

  3. Finding the leftover part: Since you indicated that your result is "3 whole groups and 1 fractional part," it seems you're looking for what fraction remains after taking the whole number.

In terms of your question about left over after grouping, when you have:

  • 3 whole groups: this accounts for \( 3 \)
  • Fractional part: since you calculated it was \( \frac{1}{2} \), not \( \frac{1}{3} \) or \( \frac{2}{3} \).

Thus, you have:

\[ \text{I have } \frac{1}{2} \text{ of a group left over.} \]

So you would fill in the blank with \( \frac{1}{2} \).
