Hope this helps, if not sorry.
To convert decimal over to percent, we move the decimal place two places to the right. So 0.5 becomes 50%.
Ok so the first thing to do would be get rid of the fraction. To do that multiply the ENTIRE equation but the denominator. Once all the numbers are multiplyed I think it’ll be easier for u to solve them :) or if u wanna solve them quick, download Photomath :)
