Diego measured the length of a pen to be 22 cm. The actual length of the pen is 23 cm. Which of these is closest to the percent increase or decrease for Diego's measurement?

4.5%

Step-by-step explanation:

From the question, we are informed that Diego measured the length of a pen to be 22 cm while the actual length of the pen is 23 cm.

The percentage decrease in his measurement will be:

= (23 - 22)/22 × 100

= 1/22 × 100

= 4.5%
