How do you work out what percentage 150000 is of 7800000000? (7.8 billion) please?

I done 7800000000 x 100 / 150000 = 5.2% is that correct?

Cancelling out zero's helps... 150000/7800000000= 15/780000= 1/52000. Converting to a percent, we multiply this by 100 to get 100/52000= 1/520= .0019230769% or .002% by rounding.

 

Hope it helps!

To help you see what you did wrong, 5% is roughly 1/20. If 150,000 was 1/20 of 7.8 billion that means that 150,000 * 20= 7.8 billion. But it doesn't showing something is wrong with your computation.

 

Hope it helps!
