84 is the mass number: 36 proton plus 48 neutrons

84 is the mass number of a stable isotope of krypton, 84Kr has 36 protons and 48 neutrons in its nucleus that give it an atomic weight of 84.

Such a number cannot be quantified. The largest multiple of 84 you can think of can always be increased by 84.

You have to set up an equation first. Which is: x will represent the boys and x+84 will represent the girls. x+x+84=436 2x+84=436 -84=-84 2x=352 2 2 x=176 So it is 176 boys and 260 girls.

x - 84
