Ariel weighed an object on her balance and recorded a mass of 24.3 grams.Her teacher told her that there was something wrong with her balance because it was giving her a reading which was 30.0% too high. What was the actual mass of the object?
For this case what we can do is the following rule of three: 24.3 -----> 130% x ---------> 100% We clear the value of x: x = (100/130) * (24.3) x = 18.7 grams Answer: the current mass of the object was: x = 18.7 grams
