Do what you did on the previous problems :P 100/100 - 21/100 = 79/100 100/100 - 6/100 = 94/100 79/100 * 94/100 * 44 = ?

This means: how many times larger is a proton then an electron? Thus we put the proton on the numerator and the electron on the denominator. From pure chemical science, a proton is wayyy bigger (and heavier) than an electron. Thus, if you get an answer that is really small ...

We need a 17% discount. We need a 5% discount as well. These discounts are on something valued at $89. If you have a 17% discount, it means you get 100/100 - 17/100 = 83/100 off the original price. In the same way, if you have a 5% discount, it means you have a 100/100 - 5/100...

Ok, 5% = 5/100. Thus, 5% tax is equal to 0.05. The tax is equal to 0.05 * (the before tax cost = 40). Then, you add the price of the ticket back. You can take a shortcut by doing 100% + 5% = 105% * 40 = 1.05 * 40 = ?

Ms. Sue is totally correct. If you want to go a little bit simpler then: 25% off something is equal to 75/100 * (the price of the "something") because 25% = 25/100. But 25% means that you take that much off, so you need to minus 25/100 from the original percentage, ...
