1% meens one(1) per(/) cent(centum100)
1/100 , so
18% meens 18/100
to multiply each term
180/1000
for a billion=10^9(a thousand millions)=1000 millions
then we could know 18% of 1 billion is 180 millions
To say on your question,
please multiply 180 million by 2.5
By another way,
2.5*10^9*0.18 or
2.5*10^9*(18/100) or
etc.…

2.5 billion is 2,500,000,000.
To find a percentage of this number, multiply by the decimal form of the percentage. 100% converts to 1 (for reference), so 18% converts to 0.18.
2,500,000,000 x 0.18 = 450,000,000
or 450 million.
