Can u please answer the question
1 answer:
Ok it is said that it is almost 15%
So we know how to round:
if it the rounding place value is 5 or more, we round upwards
If it is less than 5, it stays the same
So in this example:
The percentage is rounded up to the nearest whole number:
Look at the number after the decimal point.
14.1% ⇒ is closer to 14%
15.1% ⇒ is closer to 15%
15.8% ⇒ is closer to 16%
14.2% ⇒ is closer to 14%
14.3% ⇒ is closer to 14%
15.5% ⇒ is closer to 16%
14.4% ⇒ is closer to 14%
15.6% ⇒ is closer to 16%
14.5% ⇒ is closer to 15%
15.7% ⇒ is closer to 16%
14.6% ⇒ is closer to 15%
15.3% ⇒ is closer to 15%
14.7% ⇒ is closer to 15%
15.9% ⇒ is closer to 16%
14.8% ⇒ is closer to 15%
15.2% ⇒ is closer to 15%
14.9% ⇒ is closer to 15%
15.4% ⇒ is closer to 15%
These are the values that the percentage could have been to one decimal place:
15.1%, 14.5%, 14.6%, 15.3%, 14.7%, 14.8%, 15.2%, 14.9%, and 15.4%
