Question

there are 28 men and 72 women at a medical convention. what is the ratio of the number of men at the convention to the total number of people at the convention? write your answer as two numbers separated by a colon (for example, 2:3).

Explanation:

Step1: Find total number of people

Total people = Men + Women = \( 28 + 72 = 100 \)

Step2: Find the ratio of men to total people

Ratio of men to total people = Men : Total people = \( 28 : 100 \)
Simplify the ratio by dividing both numbers by their greatest common divisor (4): \( \frac{28}{4} : \frac{100}{4} = 7 : 25 \)

Answer:

7:25
