Understanding Percentages and Commutative Property

The video tutorial explains how to find b% of a given that a% of b equals 25. It starts by setting up the equation a/100 * B = 25, then uses the commutative property to manipulate the equation. Finally, it concludes that b% of a also equals 25.

What is the initial problem introduced in the video?

• Finding b% of a given a% of b

• Finding a% of b given b% of a

• Calculating b% of b given a% of a

• Calculating a% of a given b% of b
