Question

how do you write 21.854 in words? twenty-one and eight hundred fifty-four hundredths twenty-one and eight hundred fifty-four thousandths twenty-one and eight hundred fifty-four ten-thousandths twenty-one and eight hundred fifty-four tenths

Explanation:

Step1: Recall decimal place values

The decimal 21.854 has the whole number part 21 (twenty - one) and the decimal part 0.854. The first decimal place is tenths, the second is hundredths, and the third is thousandths. So the digit 8 is in the tenths place, 5 in hundredths, and 4 in thousandths. So 0.854 is eight hundred fifty - four thousandths.

Step2: Combine whole and decimal parts

Combining the whole number part (twenty - one) and the decimal part (eight hundred fifty - four thousandths), we get "twenty - one and eight hundred fifty - four thousandths".

Answer:

B. twenty - one and eight hundred fifty - four thousandths (assuming the second option is labeled B, if we follow the order of the options: first option is about hundredths, second about thousandths, third about ten - thousandths, fourth about tenths. The correct one is the second option which is "twenty - one and eight hundred fifty - four thousandths")
