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
