Answer 1

To determine the unit rate (distance traveled in one minute) when a caterpillar crawls \(\frac{12}{14}\) of an inch in \(\frac{14}{14}\) of a minute, you need to find out how much the caterpillar crawls in 1 minute.

The correct process to find the unit rate is to divide the distance by the time:

\[
\text{Unit rate} = \frac{12}{14} \div \frac{14}{14} = \frac{12}{14}
\]

However, since 1 minute can be represented as a whole (which is \(1\)), you can express the division as:

\[
12 \div 14
\]

The answer options provided point to the correct operation being \(12 \div 14\), which simplifies to \(\frac{6}{7}\) inches per minute.

So, for Question 2, the caterpillar can crawl \(\frac{6}{7}\) inches in one minute, and the unit rate is \(\frac{6}{7}\) inches per minute.
