Thus in your question replace the verb is by an equal sign. The word percent means per onehundred so replace percent by division by 100. The word of means multiplication. (One half of four is ^{1}/_{2} 4 = 2.) What number is the quantity you don't know so use some letter like x to stand for this number. Your question "6.9 is 11.5 percent of what number?" thus becomes
Solve for x. Check your answer, is 11.5% of your answer equal to 6.9? Penny
