Answer
To find \( 5 \div \frac{1}{3} \), multiply 5 by 3, which equals 15.
Solution
To solve \( 5 \div \frac{1}{3} \), we use the rule of dividing by a fraction which is equivalent to multiplying by its reciprocal. The reciprocal of \(\frac{1}{3}\) is \(3\), so:
\[
5 \div \frac{1}{3} = 5 \times 3.
\]
Thus, the correct multiplication equation from the options is:
\[
5 \times 3 = 15.
\]

To solve \( 5 \div \frac{1}{3} \), you can use the equation \( 5 \times 3 = 15 \). This is because dividing by a fraction is the same as multiplying by its reciprocal. In this case, the reciprocal of \( \frac{1}{3} \) is \( 3 \), so you multiply \( 5 \) by \( 3 \) to get \( 15 \). A common mistake is to simply multiply \( 5 \) and \( \frac{1}{3} \) together, which would actually give you \( \frac{5}{3} \) instead. Remember, to divide by a fraction, always change it to multiplication by its reciprocal! This little twist can save you heaps of frustration in math!
