45 + 35 = 80
45 percent of 80 = 36
If 45 = 120% then simply divide 45 by 120, to find 1%, which is 0.375 and then multiply this by 80 to find 80%, which is 30 - or - 1.20X = 45; X = 45/1.20 = 37.5; then 80% of the number is: 37.5 X .80 = 30
80 percent of 45 percent = 0.8 x 45 percent = 36 percent
36/0.8 = 45. Therefore, the number that 36 is 80 percent of, is 45.
200% of a number is 90, so 100% of a nubmer is 45, so 45 is 80% 0f a number therfore a number is 45/80*100=225/4

Its mass number is 80.Z=# of electrons=number of protons (unless it's an ion)A=Z+# of neutronsA=35+45=80
The number of neutrons is 45 because you subtract 80 to 35.
80% of 45 = 45 * 80/100 = 36
