Question

Sixteen out of twenty persons in a gym are men, and the rest are women.

What fraction of persons in the gym are men?

A)16/20
B)4/5
C)0.8
D)All of the above

Answer 1

The fraction of men in the gym is 16/20, which can be simplified to 4/5, and is also represented as 0.8. Thus, all options, 16/20, 4/5, and 0.8, are correct, making the answer D) All of the above.

Step-by-step explanation:

The fraction of persons in the gym who are men is calculated by dividing the number of men by the total number of persons. There are 16 men out of 20 people in the gym. So, the fraction is 16/20.

However, this fraction can be simplified by dividing both the numerator and the denominator by their greatest common divisor, which is 4. When we do this, we get 4/5.

Furthermore, if we convert 4/5 to a decimal, we get 0.8. Thus, we can see that all three options, 16/20, 4/5, and 0.8, represent the same value but in different forms. Therefore, the correct answer is D) All of the above.
