Answer 5

The reciprocal rule in division is that to divide two numbers, you multiply the first number by the reciprocal of the second number.

\( \large \dfrac{1}{3} \div 6\)

First look at the problem and think about it.
Let's say you have a third of a chocolate bar, and you want to divide it by 6 people.
How much will each person get? Each person will get 1/6 of 1/3. It will be a very small piece. That means that the answer A, 2, makes no sense. How can you divide 1/3 by 6 and get 2, more than you started with?

Now let's actually do it using the reciprocal rule.

\( \large \dfrac{1}{3} \div 6 = \dfrac{1}{3} \times \dfrac{1}{6} = \dfrac{1 \times 1}{3 \times 6} = \dfrac{1}{18}\)

This result makes sense. If you divide 1/3 of a chocolate bar by 6 people, each person gets 1/18 of the chocolate bar.

james' mistake above was that he forgot the reciprocal rule and multiplied by 6 instead of multiplying by the reciprocal of 6 which is 1/6.
