If you divide a number times 48 and it equals to a whole number then that is the answer! But if it has a decimal as the answer then you have to use a different number
If: m/8 -2 = 48 Then: m = 400
One third minus three sixteenths equals seven forty-eighths (1/3-3/16=16/48-9/48=7/48).
104 - 56 = 48

Rubidium's atomic number is 37 and atomic number is the same as the protons (37 protons) Protons equal electrons so there is the same number of protons and electrons (37 electrons). The atomic mass of this element is About 85, and protons and neutrons weigh about 1 so you can subtract 37 from 85 to get and 48 neutrons. 37 protons, 37 electrons and 48 neutrons.
When you minus a negative number it is the same as adding a positive number, since minus a negative number is a plus. So 48 minus (-12) is 48 + 12 = 60
