Answer:
7.6
Step-by-step explanation:
7.42 as a fraction is 7420/1000. Now you need to simplify it. The easiest way to do this is to continuously divide the top and bottom by 2 as long as it is even. At this point it should be small enough to figure out the other factors, and finish simplifying it. This only simplifies to 371/50. While 371 is divisible by 7 and 53, 50 is not divisible by either of them, so the final solution is 371/30
Therefore 371/50 is 7.42 as a fraction.
The ones which are discrete would have answers like 1234 and would not have any decimal answers so you can’t have half a student or half a chair there for those of the two that are discrete
(85 + 84 + 78 + x) / 4 = 86
(247 + x) / 4 = 86
247 + x = 86 * 4
247 + x = 344
x = 344 - 247
x = 97 <=== her score was 97
