Question

in a country , 17 out of every 20 people are literate. how many people out of 100 people in the country are literate​

Answer 1

Based on the given literacy rate of 17 out of 20, the proportional number of literate people out of 100 would be 85.

Step-by-step explanation:

The student is asking how to scale a ratio up to a different total number. In this case, we have a literacy rate of 17 literate people out of every 20. To find out how many are literate out of 100, we can set up a simple proportion:

• The ratio of literate people to total people in the original group is 17/20.
• We want to find the equivalent ratio when the total is 100.

17/20 is the same as x/100, where x is the number of literate people out of 100. To solve for x, we can cross multiply to get:

• 20x = 17 * 100
• x = (17 * 100) / 20
• x = 1700 / 20
• x = 85

Therefore, out of 100 people, 85 would be literate based on the given ratio.

Answer 2

85 people

Step-by-step explanation:

in a country , if 17 out of every 20 people are literate, then;

17 literate = 20 people

To get the number of literate people in 100

x literate = 100 people

Divide both expressions

17/x = 20/100

Cross multiply

20x = 17 * 100

x = 1700/20

x = 85

Hence 85 people are literate out of 100 people
