Please helpAnswer by solver91311(18785)   (Show Source): You can put this solution on YOUR website! In a word, no. What you suggest would be finding, in effect, the value representing 70% of 28. (even though you converted the wrong number to a decimal) Not the same question at all. Besides, the result of multiplying 28 by .7 is 19.6, and where would one find .6 of a student, some students' poor study habits notwithstanding? Still another sanity check is that if 28 is 70% of something, then that something has to be larger than 28. The question says: 28 is 70% of what? That means that you are looking for a value that when multiplied by 70% or 0.70 results in 28. A good placeholder for an "I don't know what" is x. So we need to translate the english sentence "70% of a value I don't know is 28" into algebraic symbols. '70%' means 0.70 'of' means multiply 'a value I don't know' means x 'is' means = and 28 means 28 Therefore: Now, in order to get x by itself on the left so that we know its value, we need to divide by 0.70 John
