    Direct & Inverse Proportion

    Proporcionalidade Direta e Inversa

    If 8 workers can build a wall in 6 days, how many days would 12 workers take to build the same wall?

    This is inverse proportion — more workers means fewer days. Total work = workers \times days.

    Solution

    Step 1 of 2

    1. 1.Total work = 8 \times 6 = 48 worker-days
