55.13%
Step-by-step explanation:
Your comparison is 215 men out of 390 people.
Divide 215 by 390 and then multiply by 100 to get your percentage
215 ÷ 390 = 0.5513
0.5513 × 100 = 55.13%
Answer:
Proportion states that the two ratios or fractions are equal
Given the statement:
The scale on map is 2 cm =25 miles.
Dave measured the distance to the next town at 5 cm.
We have to find the what miles away is the next town.
Let x be the distance in miles away is the next town.
By definition of proportion:
![\frac{2}{25} = \frac{5}{x}](https://tex.z-dn.net/?f=%5Cfrac%7B2%7D%7B25%7D%20%3D%20%5Cfrac%7B5%7D%7Bx%7D)
By cross multiply we get;
![2x = 5 \times 25](https://tex.z-dn.net/?f=2x%20%3D%205%20%5Ctimes%2025)
Simplify:
![2x = 125](https://tex.z-dn.net/?f=2x%20%3D%20125)
Divide both sides by 2 we get;
x = 6.25 miles
Therefore, 6.25 miles away is the next town.
