Question: 1 / 400

How many machines are actively used if 3 out of 9 are broken?

3 machines

6 machines

To determine the number of machines that are actively used when 3 out of 9 are broken, you start with the total number of machines, which is 9. If 3 of these machines are not operational, you can find the number of functional machines by subtracting the broken machines from the total.

Calculating this gives:

9 (total machines) - 3 (broken machines) = 6 (active machines).

Thus, there are 6 machines that are actively being used. The correct interpretation of the scenario involves recognizing that "actively used" refers to the machines that are functioning and available for work, resulting in the conclusion that 6 machines are operational at the time.
