# Whole numbers in written form review

CCSS.Math:

Review writing whole numbers 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, 7, end color #11accd, comma, start color #7854ab, 2, end color #7854ab, start color #1fab54, 2, end color #1fab54, start color #ca337c, 9, end color #ca337c in expanded form.

Thousands | Hundreds | Tens | Ones |
---|---|---|---|

start color #11accd, 7, end color #11accd | start color #7854ab, 2, end color #7854ab | start color #1fab54, 2, end color #1fab54 | start color #ca337c, 9, end color #ca337c |

7229, equals, start color #11accd, 7, end color #11accd, start text, space, t, h, o, u, s, a, n, d, s, end text plus, start color #7854ab, 2, end color #7854ab, start text, space, h, u, n, d, r, e, d, s, end text, plus start color #1fab54, 2, end color #1fab54, start text, space, t, e, n, s, end text, plus, start color #ca337c, 9, end color #ca337c, start text, space, o, n, e, s, end text

7229 in written form is start text, start color #11accd, s, e, v, e, n, space, t, h, o, u, s, a, n, d, end color #11accd, comma, start color #7854ab, space, t, w, o, space, h, u, n, d, r, e, d, end color #7854ab, start color #1fab54, space, t, w, e, n, t, y, negative, end color #1fab54, start color #ca337c, n, i, n, e, end color #ca337c, end text
