100.8 is one hundred and eight tenths which could be expressed as 100/1 + 8/10. Then add together (find common denominator of 10) = 1000/10 + 8/10 = 1008/10. Reduce to 504/5. Check answer by dividing 504 by 5 to get 100.8
"of" in math always means multiply. 72.8 x 120 = 8736. Because the question asks for percentage, move the decimal point in the answer 2 places to the left to get 87.36

100.8 = 10080/100 = 1008/10 = 504/5
When a number is written like 100.8 it is the same as 100.8/1. The typical thing to do is convert it to a percent by putting it over 100 then reducing and that gives you a fraction.
Convert 72.8% to decimal. 0.728
Multiply 120 by 0.728. 120 * 0.728 = 87.36
The answer is 87.36.
You can check it by converting back into a percent. (87.36 * 100)/120 = 72.8
