Question 4

Out of 222, what percentage is 122?

Accepted Answer

55 percent

Answer

To calculate the percentage of 122 out of 222, you can use the following formula:

(122 / 222) * 100

Dividing 122 by 222 gives us 0.5495. Multiplying this by 100 gives us 54.95.

Therefore, 122 out of 222 is approximately 54.95 percent.

Question 5

In only five minutes, a burrito artist can create 14 burritos. In one hour, how many burritos can she produce?

Accepted Answer

168

Answer

To find out how many burritos the burrito artist can make in one hour, we need to determine the number of 5-minute intervals in an hour.

There are 60 minutes in an hour, and since the artist can make 14 burritos in 5 minutes, the number of burritos made in one hour can be calculated as follows:

Number of burritos in one hour = (Number of burritos in 5 minutes) * (Number of 5-minute intervals in an hour)

Number of burritos in one hour = 14 * (60 / 5)

Number of burritos in one hour = 14 * 12

Number of burritos in one hour = 168

Therefore, the burrito artist can make 168 burritos in one hour.
