Answer:
this is easy. all you have to do is figure out what 18% of 389 is and then subtract that answer from 389. the easy trick i use is to make a fraction with the numerator being a question mark and the denominator being 389 (displayed below). then you would make a second fraction with 18 as the numerator and 100 being the denominator (displayed below). you would then multiply 389 with 18 and divide by 100 to get the numerator of the first fraction (which is 70.02). now you subtract 70.02 from 389 (being 318.98). this would mean that Megan has not done the math correctly.
Step-by-step explanation:
?/389 = 18/100
389 x 18 = 7002
100/7002 = 70.02
389 - 70.02 = 318.98
The change in the first round is -22.
The change in the second round is unknown, so we let x = the change in the second round.
When we add the two changes we get an overall change of 0.
-22 + x = 0
Add 22 to both sides of the equation.
x = 22
The change in the second round is 22 points because when you add 22 points to -22 points you get the overall change of 0 points.
The equivalent fraction to 8 1/3 is 25/3
