Not sure if I did this right.
A worker has readings that take minutes each to read and record. How many readings can be completed in 192 minutes?
8/3 = 192/x = 8x = 576/8 = x = 72
Answer = 72
You left out information. How many minutes each to read and record.
2 2/3
To calculate the number of readings that can be completed in 192 minutes, you need to divide the total time available (192 minutes) by the time it takes to complete one reading (x minutes).
Let's call the time it takes to complete one reading x minutes.
The equation would be: 192 minutes / x minutes = number of readings.
To solve this equation, you need to isolate x. You can cross-multiply:
192 minutes * 1 reading = x minutes * number of readings.
This simplifies to: 192 = x * number of readings.
Now, let's use the information given in the question. It states that each reading takes "minutes each to read and record." It seems like there is some missing information regarding the time it takes for a worker to complete one reading. Could you please provide that missing information?
