Which is the correct word form of 8.16
Aleksandr-060686 [28]

The <u>correct word form of 8.16</u> is b. eight and sixteen hundredths

Since the number is 8.16, we have 8.16 = 8 + 0.16 = 8 + 16/100

Since we have 8 in the units place, it is pronounced eight.

Also, we have our decimal part 0.16 = 16/100 which is pronounced as sixteen hundredths.

So, combining both we have eight and sixteen hundredths.

So, the <u>correct word form of 8.16</u> is b. eight and sixteen hundredths
