9 · Negatives & Fractions

🧩 Algebra QuestGrade 4 – Grade 5ages 9–11Pro

Solve equations whose numbers or answers are negative or fractions.

What your child learns

Example

x/3 + 2 = −1 → x/3 = −3 → x = −9.

Mini lesson: Negative Numbers & Fractions in Equations

Goal: Solve equations whose numbers or answers are negative or fractions.

The same steps work for every equation — the numbers are just trickier.
  • Answers can be negative: x + 9 = 4 → x = −5.
  • Answers can be fractions: 3x = 2 → x = 2/3.
  • To clear a fraction, multiply both sides by the denominator: x/4 = 3 → x = 12.

Worked example

Solve 2x/3 − 1 = 5.

  1. Add 1: 2x/3 = 6
  2. Multiply by 3: 2x = 18
  3. Divide by 2: x = 9
