anonymous · Answer

ok good, so now we can start the actual problem, which is to solve 
$125 is 5% of what number?

anonymous · Answer

2500

anonymous · Answer

we translate directly in to math
125 is 125
"is" is equals $=$ 
$5\%=.05$
"of" is times $\times $
"what number" is any variable. i choose $x$ and write 
$$125=.05x$$ solve for $x$

anonymous · Answer

$$125\div .05=2500$$
