Question

If someone has a networth of 7.92×10^10 .Suppose that this individual now decides to give one-eighth of a percent of his new net worth to charity. How many dollars are given to charity?

Answer 1

1 percent of his networth is:
7.92 · 10^10  : 100 = 7.92 · 10^8
One-eight of a percent is:
7.92 · 10^8 : 8 = 0.99 · 10^8  = 9.9 · 10^7 
Answer: $99,000,000
