Review writing decimals in written form, and try some practice problems.

Written form

Written form is a way to write numbers using only words.

Eksempel

Let's write start color blueD, 3, end color blueD, point, start color purpleD, 4, end color purpleD, 0, start color maroonD, 5, end color maroonD in written form.
Ones.TenthsHundredthsThousandths
start color blueD, 3, end color blueD.start color purpleD, 4, end color purpleD0start color maroonD, 5, end color maroonD
3, point, 405, equals, start color blueD, 3, end color blueD, space, o, n, e, s, plus, space, start color purpleD, 4, end color purpleD, 0, start color maroonD, 5, end color maroonD, space, t, h, o, u, s, a, n, d, t, h, s
First, we will read the number to left of the decimal.
start color blueD, T, h, r, e, e, end color blueD
Then, we read the decimal as "start color goldD, a, n, d, end color goldD".
start color blueD, T, h, r, e, e, end color blueD, start color goldD, space, a, n, d, end color goldD
Finally, we read the numbers right of the decimal and state the place value of the digit farthest to the right.
start color blueD, T, h, r, e, e, end color blueD, start color goldD, space, a, n, d, end color goldD space, start color purpleD, f, o, u, r, end color purpleD, space, h, u, n, d, r, e, d, space, start color maroonD, f, i, v, e, end color maroonD, space, t, h, o, u, s, a, n, d, t, h, s
3, point, 405 in written form is three and four hundred five thousandths.
