The number before the decimal point has a 2 in the hundreds place, a 9 in the tens place, and a 1 in the ones place. This is written as two hundred ninety-one.
The decimal point is written as "and."
The number after the decimal point has a 4 in the tenths place, a 1 in the hundredths place, and a 3 in the thousandths place. Since the last digit is in the thousandths place, this is written as four hundred thirteen thousandths.
So, the number written in words is two hundred ninety-one and four hundred thirteen thousandths.

Four hundred one is written 401. Four hundred one thousandths is written so that the last digit is in the thousandths place, 0.401.
