At Kolbens Building, 3 out of every 7 employees use public transportation. There are 9,800 employees at the building. How many use public transportation? what is the proportions

Answer 1

To find the number of employees at Kolbens Building who use public transportation, you can use the proportion of employees who use public transportation (3 out of 7) and multiply it by the total number of employees (9,800).

1. Calculate the number of employees who use public transportation:

   \[ \text{Number of employees using public transportation} = \frac{3}{7} \times 9800 \]

   \[ \text{Number of employees using public transportation} = \frac{3 \times 9800}{7} = \frac{29400}{7} = 4200 \]

So, 4,200 employees use public transportation.

2. Proportion of employees using public transportation:

The proportion of employees who use public transportation is already given as 3 out of 7.

To express this as a decimal or percentage:

\[ \text{Proportion} = \frac{3}{7} \approx 0.4286 \]

To convert this to a percentage:

\[ \text{Percentage} = 0.4286 \times 100 \approx 42.86% \]

In summary:

• Number of employees using public transportation: 4,200
• Proportion: 3 out of 7 or approximately 42.86%.
