The teacher asked 4 students to measure 4 different objects. Here are the results
posledela

Answer:

<em>Student 3 had the greatest percentage error.</em>

Step-by-step explanation:

<u>Student 1</u>

Actual length = 50in

Measured length = 49in

Error = 50 - 49 = 1

Error% = 1/50 × 100

= 1 × 2

= 2%

<u>Student</u><u> </u><u>2</u>

Actual length = 100cm

Measured length = 110cm

Error = 100 - 110 = 10

Error% = 10/100 × 100

= 10 × 1

= 10%

<u>Student</u><u> </u><u>3</u>

Actual length = 2cm

Measured length = 2.5cm

Error = 2 - 2.5 = 0.5

Error% = 0.5/2 × 100

= 0.5 × 50

= 25%

<u>Student</u><u> </u><u>4</u>

Actual length = 10ft

Measured length = 9½ft

Error = 10 - 9½ = ½

Error% = ½/10 × 100

= ½ × 10

= 1 × 5

= 5%
