56%(2/5 * 568 +7/20% * 451)

I can't make head nor tail of that bunch of numbers. You need more parentheses.

I'm not sure exactly what "7/20%" is but:

0.56(0.4*568+7/0.2*451) = 8,966.832

Edit: oops, fixed. Though newnameman seems to have the ticket.

 

[newnameman]

The answer is 56

 

[blackbishop26]

thats the problem as it appears on my sheet.

56 percent times ( two fifths percent times 568 + 7 twentieths percent times 451)

Actually no, that's not correct.

Google is interpreting the % signs in different ways. The first one gets read as modulo. So it's computing 56 mod (the other terms).

The second one is being read as percent, i.e. 20% = 0.2.

It is clear that modulo is never the correct interpretation because a/b% * c doesn't make sense if % means mod. And the result of (the other terms) is a decimal, and mod is an integer op.

Anyway, the answer is: 8966.832

I get 8966.832 following order of operations. It's possible the answer could be different if it were written with more parenthesis, but if that's all that's written, then this is the correct answer.

If this is eaxctly the original problem statement, try this:

"two fifths percent" is 0.4 percent or 0.004 as a fraction. So "two fifths percent times 568" comes to 2.272. Similarly, "7 twentieths percent times 451" is 0.35% x 451 = 1.5785. Now we're at "56 percent times (3.8505)" = 2.15628.
