To find out what number 72 is 90% of, you can set up the equation as follows: let \( x \) be the unknown number. You can express this mathematically as \( 0.9x = 72 \). Solving for \( x \), you'll divide both sides by 0.9, giving you \( x = \frac{72}{0.9} \), which simplifies to 80. So, 72 is 90% of 80! If you want a fun tip, remember that percentages are like slices of pizza—if you have a whole pizza (100%), 90% is almost the entire thing! Just think, if 72 is the amount of pizza you’ve eaten, you’ve devoured just about all of it, leaving only a slice behind! And keep your fractions handy; they can help with such calculations on the fly!
