Approximate the smallest decimal fraction that can be formed using the digits 2, 4, 7, and 0 to the nearest hundredth.
To write the smallest decimal fraction, put the decimal point (0.), then write the digits arranged in ascending order from the left to the right. So the smallest decimal fraction formed using the digits 2, 4, 7, and 0 is 0.0247.
To approximate to the nearest hundredth, look at the digit in the thousandths place. 4 is less than 5, so leave out the digit at the thousandths place and any other digits to the right.
