this is the only one on the paper i cant figure out... geh
2% of what number is 15?
let the number be x
so (20/100)x = 15
can you solve that little equation?
I am sure you can finish it up.
Is that 20% or 2%?
taking a second look....
oops, sure looks like 2%
a quicker way than I showed before:
15 ÷ .02
