Since you don't have a problem for me to solve I'll just give you an example.

lets say the fraction is 1/4 you need to multiply both sides by 25 so the denominator is 100. it's easier to put a number in decimal form whecn the denominator is either 10, 100, 1000, and so on. the answer would then be 25/100 which then equals .25 which is 25 hundredths.

The formula is b^x=a is the same as log{b}a=x. So in your problem b=3, x=7 and a=2137. Then you plug it into the log part of the equation. log(3)2137=7.
