Final answer:
To find the total number of people in the senior center dining room, divide 80 (the number of men) by 2/5, which results in a total of 200 people.
Step-by-step explanation:
The question asks to find the total number of people in the senior center dining room given that two-fifths of them are men and there are 80 men. To solve this, we can set up the equation (2/5) × total number of people = 80 men. We can then divide both sides of the equation by (2/5) to find the total number of people.
Here is how you do the calculation step by step:
- Write out the equation: (2/5) × total number of people = 80
- Divide both sides of the equation by (2/5) to isolate the total number of people on one side: total number of people = 80 ÷ (2/5)
- Calculate the total number of people: total number of people = 80 ÷ 2 × 5 = 200
Therefore, the total number of people in the senior center dining room is 200.
