Calculating the Number of Parts Made by the Apprentice

To calculate the number of parts made by the apprentice, we can use the following steps:

1. Total Number of Parts: The total number of parts made by the locksmith and his apprentice is 1200. 2. Percentage Made by the Apprentice: The apprentice made 30% of all the parts.

Calculation

To find out how many parts the apprentice made, we can use the following formula: \[ \text{Number of parts made by the apprentice} = \text{Total number of parts} \times \left( \frac{\text{Percentage made by the apprentice}}{100} \right) \]

Solution

Using the given values: \[ \text{Number of parts made by the apprentice} = 1200 \times \left( \frac{30}{100} \right) \] \[ \text{Number of parts made by the apprentice} = 1200 \times 0.30 \] \[ \text{Number of parts made by the apprentice} = 360 \]

The apprentice made 360 parts.
