91 x 100/65 ie 140
The element proactinium-231 has 140 neutrons (element number 91, 91 protons).
so in other word you need to put it into a number model, 91 is 65percent of ( times) blank....... 65percent * blank = 91 . So you have to divide 65 by 91 and u round that number . so the answer is 140
91 + 49 = 140
91! = 1.352001527678 E+140
140
35 percent of 91 percent = 0.35 x 91 percent = 31.85 percent
140 = 14,000 percent
