Question

Clea estimates that a glass contains 250.55 mL of water. The actual amount of water in the glass is 279.48 mL.

To the nearest tenth of a percent, what is the percent error in Clea's estimate?

Answer 1

Ok take 279-250=29 then take 29/100=11.6 then take 11.6*100=11.6% So 11.6 is the answer. To recheck take 250*0.116=29 then 250+29= 279.

11.6%
