This sharing by Ben Stephens is considered "surprising" and makes the calculation easier than you think.

This formula is not complicated at all.

The simple formula is x% of y = y% of x. “If you want to calculate 4% of 75, just reverse it and calculate 75% of 4. That's obviously much simpler.”

According to him, this calculation is as simple as calculating 18% of 50 which is difficult but 50% of 18 is easy, all of which equal 9.

This recipe received over 21,000 likes and many rave comments.

They thought it was a great way to calculate and could help many people. Some even asked Ben Stephens to tutor them. “I’m not a teacher or a mathematician. I just found it interesting and shared it on Twitter. Interestingly, this has become my most popular post ever,” he wrote.
