Give two details to support this statement: keeping your nails trimmed to the right length is important. btw in the picture there is the question and information. sorry i am editing this right 's not math it's science sorry for my mistake.

When nails are too long lots of bacteria will live in there. They can also become ingrown and scratch people easily.

Percent Error is used in comparing the actual/ exact value to the estimated/ guess value.
First, you need to subtract the actual value from the estimated value. If there is a negative answer, ignore or disregard the sign. In your given data, 1081 less 1150 will equal to -69. Again, disregard the negative sign, so it will only be 69.
Next, divide your answer by the exact value (which is 1150). So 69 divide by 1150 will come up to our final answer which is 0.06 or 6% if we round it off.
FINAL ANSWER IS 6%.
