Splitting a Fraction over Its Numerator

This video presents the same text shown beside it, spoken and on screen. It adds nothing the text does not say.

State

A fraction splits across the terms of its numerator: (a + b)/c = a/c + b/c — the denominator serves each term.

Show

(6 + 9)/3 is 15/3 = 5, and 6/3 + 9/3 is 2 + 3 = 5. Same value by both routes.

Watch for

The split runs over the top only.

Builds on

  • Nothing — this is a starting point.

Unlocks

  • Nothing yet depends on this.
