32 is _____ % of 100?

3 is 5% of what number?

81 is what % of 2700?

Let's look at all the words.
81 is a number, so we don't have to change that.

"Is" means "="

"What" is the question word. So we can put a question mark. "?"

% is "divided by 100." "/100."

"Of" means multiply. "x"

2700 is a number. Keep that the same.

81 = ?/100 x 2700

81/2700 = ?/100

.03 = ?/100

3 = the percent.

3%
