Question

Ariel weighed an object on her balance and recorded a mass of 23.9 grams. Her teacher told her that there was obviously something wrong with her balance because it was giving her a reading which was 30.4% too high. What was the actual mass of the object?

Answer 1

Rounded: 16.34

Explanation:

The OG(original) mass is 23.9 grams.

30.4% is too high of the actual mass.

Find out 69.6% of 23.9.

Set up problem.

x 69.6%

______ = ______

23.9 100%

Find x.

69.6 x 23.9 = 1,663.44

1,663.44/100 = 16.344

= 16.344

Not sure if this is correct but I tried my best. :)
