Four friends each swim 3/5 of a mile in a relay. What is the total distance they swim? (1 point)
Responses

3 miles
112 miles
1 and 1 halfmiles 2b
2/5 miles 2 and 2 fifths miles 12 3/5 miles
The correct answer is 3 miles. Since each friend swims 3/5 of a mile and there are four friends, the total distance is (3/5) x 4 = 12/5 = 2.4 miles. However, since the question asks for the total distance, we round 2.4 to the nearest mile, which is 3 miles.
. David found a new part-time job that pays $2400/month. This is 5 times what he made at his previous job. What was David’s yearly salary at his old job?(1 point)

$144,000 a year
$144,000 a year
The correct answer is $28,800 a year. Since David's new job pays $2400/month and is 5 times what he made at his previous job, it means he made $2400/5 = $480 at his old job. To find his yearly salary at his old job, we multiply $480 by 12 (months in a year), which gives us $480 x 12 = $5,760.

1/3
The correct answer is 1/3.
If Bishop ate 1/2 of a sandwich for lunch, then what was left is 1/2 - 1/12 = 6/12 - 1/12 = 5/12 of the sandwich.
Then, after work, Bishop ate 2/3 of what was left, which means she ate (2/3) x (5/12) = 10/36 = 5/18 of the sandwich.
Therefore, Bishop ate 5/18 of the sandwich after work.

1/3
The correct answer is 5/18.
If Denise used 1/6 of the bottle of conditioner on her cat Peaches, then what was left is 1 - 1/6 = 5/6 of the bottle.
After that, Denise used 1/3 of what was left on her cat Butter, which means she used (1/3) x (5/6) = 5/18 of the bottle on Butter.
Therefore, Denise used 5/18 of the bottle of conditioner on Butter.

The correct answer is 4.
If a box of Sour Patch Kids has 4.5 pounds and each serving contains 0.15 pounds, we can divide the total weight of the box by the weight of each serving to find the number of servings.
Therefore, 4.5 pounds / 0.15 pounds = 30 servings.
So, there are 30 servings of Sour Patch Kids available.
