What percentage is 50 million out of one billion?

10^6 = 1 Million

1000000=1 Million

50 Million = 50*1000000=50000000

10^9 = 1 Billion

1000000000= 1 Billion

let x% of 100000000(1 Billion)= 50000000(50 Million )

Therefore (x/100) * 1000000000=50000000

x=(50000000*100)/1000000000

x=5

Therefore 5% is 50 million out of one billion

Answer : 5%
