Answer:

Michelle must get an 80 on her next test to keep her average score.

Step-by-step explanation:

Since Michelle got an average score of 80 on two tests, to determine what score she must get on the third test so that her average score for the three tests is the same as the average score for the first two tests, the following calculation must be performed:

X / 2 = 80

X = 80 x 2

X = 160

X x 3 = 80 x 3

X x 3 = 240

X = 240/3

x = 80

So, Michelle must get an 80 on her next test to keep her average score.

63 12/60 simplified

Andreas93 [3]

Your question is not clear, if you are asking: what is $63 \frac{12}{60}$ simplified? Then the answer is $63 \frac{1}{5}$ or $63.2$ .

If 63 is just the question number and you are asking, what is $\frac{12}{60}$ simplified. Then the answer is $\frac{1}{5}$ or $0.2$

You get this answer by finding the highest number that both the numerator and denominator are divisible by, and diving both numbers by that:

$\frac{12}{60} \div \frac{12}{12} = \frac{12 \div 12}{ 60 \div 12} = \frac{1}{5} = 0.2$
