To write: The decimal number for one hundred six and twenty-seven ten-thousandths.

Answer to Problem 1P

The decimal number for one hundred ten and twenty-one thousandths is 106.0027.

Explanation of Solution

Obtain the decimal number for one hundred six and twenty-seven ten-thousandths as follows.

Write the whole number part which is before the “and” part.

As there is “and” part in one hundred six and twenty-seven ten-thousandths, the whole part will be 106.

So, the whole part is followed by the decimal point.

As the decimal part is ten-thousandths, draw four blanks such as $106.\underset{\_}{}\underset{\_}{}\underset{\_}{}\underset{\_}{}$.

Write the number twenty-seven on the far right blank such as, $106.\underset{\_}{}\underset{\_}{}\underset{\_}{2}\underset{\_}{7}$.

Therefore, the decimal number for one hundred ten and twenty-one thousandths is 106.0027.
