Convert Decimal 0.80 to Words: Reading Hundredths

Q: Why is 0.80 written as 80/100 instead of 8/10?

Even though $ \frac{80}{100} $ equals $ \frac{8}{10} $, the decimal 0.80 has two decimal places, so we read it exactly as written: eighty hundredths.

Q: Does the zero at the end of 0.80 matter?

Yes! The trailing zero shows the decimal goes to the hundredths place. Without it, 0.8 would be read as "eight tenths" instead of "eighty hundredths."

Q: How do I know what denominator to use?

Count the decimal places! One decimal place = tenths (denominator 10), two decimal places = hundredths (denominator 100), three places = thousandths (denominator 1000).

Q: Is 80/100 the same as 8/10?

Mathematically yes - they're equivalent fractions. But when converting 0.80 to words, we read it exactly as the decimal shows: "eighty divided by one hundred."

Q: What if I wrote 0.8 instead of 0.80?

That would be 8/10 or "eight tenths." The extra zero in 0.80 specifically indicates hundredths place value, so we must include all 80 parts out of 100.
