The world’s smallest vegetable is the snow pea. It measures about 0.25 inches in diameter. Which phrase correctly represents this value? a) Twenty-five hundreds, b) twenty-five, c) twenty-five tenths, d) twenty-five hundredths, or e) twenty-five thousandths.

We need to think about place value. Our number is 0.25. To the left of the decimal is the tens place. The first digit to the right of the decimal place is the tenths place. The second digit to the right of the decimal place is the hundredths place.

It looks like we have two tenths and five hundredths. But there’s another way to say this. Two tenths is equal to twenty hundredths. Twenty hundredths plus five hundredths equals 25 hundredths.

0.25 is equal to 25 hundredths. We can write the number 25 in words like this and then add the word hundredths. Answer choice d is the only one that matches — twenty-five hundredths.
