Responses
1 7/15
8/15

3/4
To find the fraction of teenagers who mainly exercise by walking, we need to find the fraction of teenagers who said they got regular exercise and then find the fraction of those who said that walking was their main form of exercise.
⅔ of the teenagers responded that they got regular exercise.
Out of those who said they got regular exercise, ⅘ said that walking was their main form of exercise.
Therefore, the fraction of teenagers who mainly exercise by walking is ⅔ * ⅘ = 6/15 = 2/5.
The correct answer is 2/5.
To find the fraction of teenagers who mainly exercise by walking, we need to multiply the fractions that represent the proportions of teenagers who do regular exercise and the proportion of those who walk as their main form of exercise.
The first step is to find the fraction of teenagers who do regular exercise. The survey states that ⅔ of teenagers responded that they get regular exercise. So, the fraction of teenagers who do regular exercise is ⅔.
Next, we need to find the fraction of those who do regular exercise and walk as their main form of exercise. The survey states that ⅘ of those who do regular exercise said that walking was their main form of exercise. So, the fraction of teenagers who mainly exercise by walking is ⅘ of ⅔.
To multiply fractions, we multiply the numerators to get the new numerator, and we multiply the denominators for the new denominator.
⅘ * ⅔ = (8 * 3) / (5 * 2) = 24/10 = 12/5
Therefore, the fraction of teenagers who mainly exercise by walking is 12/5.
However, the given answer choices don't include 12/5 as an option. They only provide 1 7/15, 8/15, 6/8, and 3/4. Therefore, none of the given answer choices is correct based on the information provided.
To find the fraction of teenagers who mainly exercise by walking, we need to multiply the fractions that represent each step of the information given.
⅔ of teenagers responded that they got regular exercise, and ⅘ of those said that walking was their main form of exercise.
Step 1: Find the fraction of teenagers who said that walking was their main form of exercise.
⅔ * ⅘ = 8/15
Therefore, the fraction of teenagers who mainly exercise by walking is 8/15.
you have to pick the correct answer that was listed in the options.
I apologize for the confusion. In that case, looking at the given answer choices, the closest fraction to 8/15 is 6/8. Therefore, 6/8 is the correct answer.
Clarissa cycled at 12 1/2 miles per hour for 2 ½ hours. How far did she travel?(1 point)

To find the distance Clarissa traveled, we need to multiply her speed (12 1/2 miles per hour) by the time she traveled (2 1/2 hours).
First, let's convert 12 1/2 to an improper fraction: 12 1/2 = 25/2
Next, let's convert 2 1/2 to an improper fraction: 2 1/2 = 5/2
To multiply fractions, we multiply the numerators to get the new numerator, and we multiply the denominators for the new denominator.
(25/2) * (5/2) = (25 * 5) / (2 * 2) = 125/4 = 31 1/4
Therefore, Clarissa traveled a distance of 31 1/4 miles.
The correct answer is 31 and 1/4.
Compute: 9/11
÷ 1/3
. Simplify the answer if possible.
To divide fractions, we need to multiply the first fraction by the reciprocal of the second fraction.
The reciprocal of 1/3 is 3/1.
So, 9/11 ÷ 1/3 is equivalent to 9/11 * 3/1.
To multiply fractions, we multiply the numerators to get the new numerator, and we multiply the denominators to get the new denominator.
(9/11) * (3/1) = 27/11
Therefore, 9/11 ÷ 1/3 simplifies to 27/11.
