Decimals in written form review

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

Written form

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

Example

Let's write start color #11accd, 3, end color #11accd, point, start color #7854ab, 4, end color #7854ab, 0, start color #ca337c, 5, end color #ca337c in written form.
Ones.TenthsHundredthsThousandths
start color #11accd, 3, end color #11accd.start color #7854ab, 4, end color #7854ab0start color #ca337c, 5, end color #ca337c
3, point, 405, equals, start color #11accd, 3, end color #11accd, start text, space, o, n, e, s, end text, plus, start color #7854ab, 4, end color #7854ab, 0, start color #ca337c, 5, end color #ca337c, start text, space, t, h, o, u, s, a, n, d, t, h, s, end text
First, we will read the number to the left of the decimal.
start color #11accd, start text, T, h, r, e, e, end text, end color #11accd
Then, we read the decimal as "start text, start color #e07d10, a, n, d, end color #e07d10, end text".
start color #11accd, start text, T, h, r, e, e, end text, end color #11accd, start color #e07d10, start text, space, a, n, d, end text, end color #e07d10
Finally, we read the numbers to the right of the decimal and state the place value of the digit farthest to the right.
start color #11accd, start text, T, h, r, e, e, end text, end color #11accd, start color #e07d10, start text, space, a, n, d, end text, end color #e07d10 start text, space, start color #7854ab, f, o, u, r, end color #7854ab, space, h, u, n, d, r, e, d, space, start color #ca337c, f, i, v, e, end color #ca337c, space, t, h, o, u, s, a, n, d, t, h, s, end text
3, point, 405 in written form is three and four hundred five thousandths.
