What is 65% of 45 Do not round the answer???
2 answers:
So I used a percent proportion to solve this question. On the left I have 65 over 100 since that is equivalent to 65%. I put that equal to x, our unknown, over 45. 45 goes on the bottom because 45 is the "whole". We are trying to find a part of that 45. An easy way to identify this is the is, of rule. If the question asks "40 is 40% of what number?" Then you are trying to identify the whole. You can identify that by noticing that the unknown comes after the word of. In your case, the unknown comes before is, showing us that we need to find the part. The part goes on the top and the whole goes in the bottom(refer to picture above). This method doesn't always work in word problems, however, because it may be worded in a tricky way. Anyways, after everything is set up, you multiply across as shown by the arrows. So 65•45 and 100•x resulting in my second step. You have 100x=2925. This has now become a one step equation. You simply need to isolate the variable, so divide both sides by 100 to get an answer of x=29.25. Hope this helped!!!
