How do you read 22.1086 ?

• twenty dot one thousand sixty-eight

• twenty two and one thousand eighty-six

• twenty two and one thousand eighty-six ten thousands

• twenty two and one thousand eighty-six ten thousandths

Answer explanation

the correct answer is twenty two and one thousand eighty-six ten thousandths (22.1086) . Why?

1) to read decimal numbers, read it like normal. For example:

11 = eleven

8201 = eight thousand two hundred one

2) instead of pronouncing the '.' or as we call dot, you pronounce it and.

example:

1.1 = one 'and' one tenths

3) like place values, we have;

ones, tens, hundreds, thousands and ten thousands

but the ones is the dot and instead those kinds of values, we add 'ths' at the end of them replacing the normal s to a ths.

4) after those explanations, we move to no. 4 which you combine all of those;

22.1086 = twenty two and one thousand eighty-six ten thousandths.
