Which length is longer 21.5 inches or 21.05 inches?
To determine which length is longer, we can compare the two lengths by looking at the hundredths place. In this case, 21.5 inches is longer than 21.05 inches because 21.5 has a higher value in the tenths place than 21.05. The tenths place is the second digit after the decimal point, so 21.5 is longer than 21.05 by 0.45 inches.
