Question

I know the answer to this equation as per the answer in the screenshot I attached I would just like to know what number is the divisor and which numbers are the dividend in these kinds of problems (specifically this one) I would also mention that I have a test tomorrow so please be speedy about this.

Before a visit to the vet, Bridget used a bathroom scale to weigh her cat, Muffin. The bathroom scale said Muffin weighed 8 pounds. The scale at the vet's office was more precise, and it showed Muffin's weight as 8.2 pounds. What is the percent error for the bathroom scale's measurement?

Round to the nearest hundredth for your decimal before converting.

Answer 1

The divisor is the accurate weight (8.2 pounds), and the dividend is the difference between the measured and accurate weights (0.2 pounds).

The percent error is calculated as (difference / accurate value) x 100 and then rounded to the nearest hundredth, resulting in 2.44% for this problem.

Step-by-step explanation:

To calculate the percent error for the bathroom scale's measurement:

Determine the accurate value, which is 8.2 pounds (according to the vet's precise scale).

Determine the measured value, which is 8 pounds (according to Bridget's bathroom scale).

Calculate the difference between the accurate and measured values:

= 8.2 - 8

= 0.2 pounds.

Calculate the percent error:

(difference / accurate value) x 100

= (0.2 / 8.2) x 100.

Round the result to the nearest hundredth: 2.439%, rounded becomes 2.44%.

In this case, the divisor is the accurate value (8.2 pounds), and the dividend is the difference between the measured value and the accurate value (0.2 pounds).

The operation involves division because you are dividing the difference by the accurate value to find the percent error.
