Final answer:
To solve for 'b' in the equation (bc)/d, we multiply both sides by 'd' and divide by 'c'. The correct and simplified answer is b = c.
Step-by-step explanation:
The question provided is asking us to solve for the variable 'b' in the equation (bc)/d. To isolate 'b', we need to remove 'c' and 'd' from being multiplied and divided respectively with 'b'. We can accomplish this by multiplying both sides of the equation by 'd' and dividing by 'c', which will leave 'b' on one side of the equation. The operations cancel out the 'd' on the left side and the 'c' on the right side, leaving us with the solution for 'b'. Therefore, the correct answer is b = (cd)/d, and this simplifies further to b = c because 'd/d' equals 1.
