A GPA of a 3.2 is equivalent to a B grade. A 4.0 is equivalent to  an A grade. It is very important to have a good GPA in high school.
On each sticker is a number. The number tells you how the fruit was grown. A 4 digit number means it was conventionally grown (using chemicals). A 5 digit number beginning with a 9 means it was grown organically. 5 digit number beginning with an 8 means it was genetically modified. So by looking at the photo of the dole banana you know it is organic because of the 5 digit number beginning with 9, although in this case the sticker also proudly says âOrganicââeven easier.
The number on the lower left of the symbol is the atomic number (or the number of protons). You will also notice that all of these have the same atomic number because they are all carbon atoms. The top number equals the number of protons plus the number of neutrons. This is called the mass number. So on the first one, the mass number is 12 indicating that the total number of protons and neutrons is 12.
