Modul 3: Decimaltal skrevet opdeltGennemgang af decimaltal skrevet opdelt
Gennemgå hvordan man skriver decimaltal opdelt og løs nogle opgaver.
Tal skrevet opdelt
At skrive tal opdelt betyder, at vi skriver et tal som en sum af værdien af hvert ciffer.
Vi kan bruge et skema med pladsværdier til at finde værdien af hvert ciffer.
Eksempel
Lad os skrive start color #11accd, 3, end color #11accd, comma, start color #7854ab, 4, end color #7854ab, start color #1fab54, 0, end color #1fab54, start color #ca337c, 5, end color #ca337c opdelt.
| Enere | , | Tiendedele | Hundrededele | Tusindedele |

3, comma, 405, equals, start color #11accd, 3, end color #11accd, start text, space, e, n, e, r, e, end text plus, start color #7854ab, 4, end color #7854ab, start text, space, t, i, e, n, d, e, d, e, l, e, space, end text, plus start color #1fab54, 0, end color #1fab54, start text, space, h, u, n, d, r, e, d, e, d, e, l, e, end text, plus, start color #ca337c, 5, end color #ca337c, start text, space, t, u, s, i, n, d, e, d, e, l, e, end text
empty space, equals, left parenthesis, start color #11accd, 3, end color #11accd, dot, 1, right parenthesis, plus, left parenthesis, start color #7854ab, 4, end color #7854ab, dot, start fraction, 1, divided by, 10, end fraction, right parenthesisplus, left parenthesis, start color #1fab54, 0, end color #1fab54, dot, start fraction, 1, divided by, 100, end fraction, right parenthesis, plus, left parenthesis, start color #ca337c, 5, end color #ca337c, dot, start fraction, 1, divided by, 1000, end fraction, right parenthesis
3, comma, 405 skrevet opdelt er start color #11accd, 3, end color #11accd, plus, start color #7854ab, start fraction, 4, divided by, 10, end fraction, end color #7854ab, plus, start color #ca337c, start fraction, 5, divided by, 1000, end fraction, end color #ca337c.
