Multiplying out decimals and fractions
- Pen and paper noted just repeat exactly what's below so no link needed.
Learning checklist
- When multiplying away decimals, no need to multiply what's in the brackets, only the bracket multiplier
- For fractions find the LCD of all fractions. Multiply by that.
- If the numbers seem too big, did you miss simplifying a fraction?

5(7+7) = 70

NOT:
0.5(7+7) = 7
