That's correct.
Think of it this way:
19/100 = 19%
75/100 = 75%
250/100 = 250%

So, 1000/10 = 10,000/100 = 10,000%

Hi anju_c_m,

There's a big 'take away' from Brent's example - if you EVER are unsure about how how a math rule/formula/pattern "works", then you should come up with a simple example (or two) and note the results. Math is all about patterns, and the 'rules' never change - so once you define how some simple examples work, then you can use that knowledge to define how a trickier-looking example works. In this case, we needed to define how fractions convert to percents; once that pattern is defined, answering the given question becomes a lot easier.

You could also remember that

p/100 = p%

So if you've got 1000/10, that's equivalent to 10000/100, or 10000%.

It's not the best worded problem, though, since %s are usually taken from some base (e.g. "1000/10 is what percent of x?"). Simply saying "what percent is 1000/10" is a little unnatural.
