Into percent equations

I know, been awhile!

We've been working (yesterday, but not today because of block schedule) on percent equations. These are things that look like not only

40% of 60 is...

but also

45 is 20% of what number...

AND

34 is what percent of 64...

To study these, I am using the metaphor of "decoding" -- we have to decode the english into math language in order to solve the problem. We just started this yesterday--and the reason why you didn't see any homework come home is because we hit a wall!

I'm hoping to remedy this tomorrow in class. :)
