6.4 is what percent of 16,000?

i am confused about the notion. does it mean 6.4 *x% = 16000? or 6.4*x=16000? the first x will equal to 100 times the second x.

thanks!

Look at the following structures:

1. a is what percent of b?

2. What percent of a is b?

Rule of thumb1: Where you encounter 'is', there you put '='.

Rule of thumb2: Where they say 'what percent', there you put 'x%' and then find x.

1. a = x% of b = (x/100) * b

2. x% of a = b = (x/100) * b

The question says: 6.4 is what percent of 16,000?

6.4 = x% of 16000

6.4 = (x/100) * 16000

x = 6.4/160 = 0.04

Answer: 0.04%
