If Kayla left a $10.47 tip on a breakfast that cost $87.25, what percentage was the tip to compare with the price of the meal?

If you want to know what percent A is of B, you divide A by B, then take that number and move the decimal place two spaces to the right: \(10.47 \div 87.25 = 0.12\)
Move the decimal two spaces to the right to find the percentage 12%.
