Question

In a park, 3 out of 7 people are adults and the rest are children. Based on the given information, how many can you predict are NOT adults if there are a total of 1400 people?

Answer 1

800 people aren’t adults bc 1400/7=200 and 4x200=800

Answer 2

To find out how many people are not adults among a total of 1400 people, when 3 out of 7 people are adults, one must calculate 1400 × (4/7), which equals 800. Therefore, 800 people are predicted to be not adults.

Step-by-step explanation:

The question asks us to predict how many people are not adults in a park where 3 out of 7 people are adults. If there are a total of 1400 people in the park, to find out how many are not adults, we must first determine the fraction representing children. Since 3 out of 7 are adults, the remaining 4 out of 7 are children.

To calculate the number of people who are not adults, we multiply the total population by the fraction representing children:

1. Total population = 1400
2. Fraction representing children = 4/7
3. Number of people who are not adults = Total population × Fraction representing children = 1400 × (4/7)
4. This gives us: 1400 × (4/7) = 800

Therefore, we can predict that 800 people in the park are not adults.
