Expressed as a percentage, rounded to two decimal places, 21/89 x 100 = 23.60 percent.
It is already in two decimal places as 0.72
Two decimal places means two numbers after the decimal point. (which looks like a period)
It is 0.69 to two decimal places
It can't be expressed exactly as a percentage, as it is one sixth as a fraction. As a decimal it is 0.166666........ recurring, so it can't be expressed exactly that way. So rounding it up to two decimal places it would be 16.67% as a percentage.
It is rounding a decimal representation of a number so that there are two digits after the decimal point.
