What do you think?  Isn't 33 1/3% exactly 1/3?

anonymous · Answer

Yea. It's 33.333333333333333333 and so on...

tkhunny · Answer

Okay,

100% of 30 is 30
200% of 30 is 60
50% of 30 is 15
25% of 30 is 7.5

Now we have a rough estimate.  What's the exact answer?

I dunno. I'm confused...That's not how my teacher taught us so...yeah.

I'm trying to coax you into showing some work.  My little display was ONLY to give an estimate so that you don't wander off.  Since 33 1/3% is between 50% and 25%, your answer should be between 7.5 and 15.  If you get 48, that's no good.

I always like to have an idea before I proceed.  It helps avoid errors. If your teacher showed you a way to proceed, why don't you proceed that way?  Let's see it.
