If you mean 11.72/237.4*100, then do 11.72/237.4. That gets you approximately 0.0493.
Then, multiply that by 100. This gets you 4.93. The answer to 11.72/237.4*100 is approximately 4.93.
However, if you mean 11.72/(237.4x/100), it is a bit different. First, solve what's in the parentheses. 237.4x/100 is just the same equation without x, and then adding x back at the end. 237.4/100 is 2.374. This means the answer to that is 2.374x. Next, you must multiply 2.374x by 11.72. Multiply the two numbers without x, and then add x back at the end. 2.374*11.72 is 27.82 (when rounding to the nearest hundredth). Add x and you have 27.82x. In conclusion, 11.72(237.4x/100) is approximately 27.82x.
