The correct operations needed to solve this problem using the equation b/8 + 25 = 500 are subtraction and multiplication.
The correct operations needed to solve this problem using the equation are subtraction and division, as the equation b/8 + 25 = 500 represents the given information.
To solve the equation for 'b' (the number of beads Niel started with), you need to isolate 'b' on one side of the equation. To do this, you can start by subtracting 25 from both sides of the equation:
b/8 + 25 - 25 = 500 - 25
Simplifying the equation gives:
b/8 = 475
Now, to find the value of 'b', you can multiply both sides of the equation by 8:
8 * (b/8) = 475 * 8
The 8 on the left side cancels out, leaving:
b = 3800
So, Niel started with 3800 beads.
