Answer 3

Calculation of the Number of Parts Produced on the Second Day

To calculate the number of parts produced by the worker on the second day, we need to determine the number of parts produced on the first day and subtract it from the total number of parts produced.

According to the information provided, the worker produced 450 parts in total. On the first day, the worker produced 60% of the total number of parts.

To find the number of parts produced on the first day, we can calculate 60% of 450:

Number of parts produced on the first day = 60% of 450 = 0.6 * 450 = 270 parts.

To find the number of parts produced on the second day, we subtract the number of parts produced on the first day from the total number of parts:

Number of parts produced on the second day = Total number of parts - Number of parts produced on the first day = 450 - 270 = 180 parts.

Therefore, the worker produced 180 parts on the second day.
