To determine the kilograms of dried fruits crushed in one minute, we need to find out how many kilograms are crushed in one minute based on the given rate.
The processing machine crushes \(3 \frac{1}{4}\) kilograms in \( \frac{3}{4} \) minute. To find out how many kilograms this machine can crush in one full minute, we can use the division of the total kilograms by the time in minutes and then multiply by 1 minute (or simply find the rate per minute).
Thus, the correct process will be:
\( \frac{3 \frac{1}{4}}{\frac{3}{4}} \)
This calculation will show how many kilograms per minute the machine can crush.
So, the answer is:
3 1/4 ÷ 3/4.
