An inspector found 40 defective batteries during an inspections. If this is 2.5% of the total number of batteries inspected, how many batteries were inspected?

1600batteries

Step-by-step explanation:

Let the number of inspected battery be y

2.5% of y = 40

5/2% of y = 40

Change 5/2% to fraction

5/200 × y = 40

5y/200=40

Cross multiply

5y= 40×200

5y=8000

y=8000÷5

y=1600

The total number of battery inspected is 1600.
