Write 0.8 in words.
Saying this value out loud, we sometimes say zero decimal eight. But that doesn’t tell us about the value. If I was going to read it in a different way, I would read it as eight tenths.
Then the first word I would write would be eight, e-i-g-h-t. The second word is tenths, t-e-n-t-h-s, eight tenths. The t-h-s on the end tells us that we’re dealing with a decimal place. We’re dealing with a number that’s smaller than one.
