Question

What is the greatest possible error if Bruce measured a buckle as 3.2 cm using the ruler?

Answer 1

Answer:

The greatest possible error for the measurement 3.2 cm is 0.05 cm.

Step-by-step explanation:

Given : Bruce measured a buckle as 3.2 cm using the ruler   

To find :  What is the greatest possible error?

Solution :

The greatest possible error in a measurement is half of the measuring unit.

Measurement 3.2 cm.    

3.2 was measured to the nearest tenth of a cm or 0.1 cm

So the measuring unit is 0.1.

The GPE is half of 0.1

i.e, $\frac{0.1}{2}=0.05$

Therefore, The greatest possible error for the measurement 3.2 cm is 0.05 cm.
