Answer 1

1)12*8=96
2)144-96=48
3)48:6=8

Answer 2

Calculating the Production Rate

To calculate the production rate of the apprentice, we can use the information provided about the number of parts produced by the turner and the time worked by both the turner and the apprentice.

The turner worked for 8 hours and produced 12 parts per hour, resulting in a total of 96 parts produced by the turner. The turner and the apprentice together produced 144 parts. Therefore, the apprentice must have produced the remaining parts.

Calculating the Apprentice's Production Rate

To find out how many parts the apprentice produced per hour, we can use the following formula: \[ \text{Parts produced by the apprentice} = \frac{\text{Total parts} - \text{Parts produced by the turner}}{\text{Hours worked by the apprentice}} \]

Substituting the given values: \[ \text{Parts produced by the apprentice} = \frac{144 - 96}{6} = \frac{48}{6} = 8 \]

The apprentice produced 8 parts per hour.
