Answer: 86

Step-by-step explanation: You would add up all the numbers, then divide by the amount of numbers there are.

For example

79+89+90=258

Since there are three numbers(79,89,90) you would divide 258 by 3 and would get 86.

Hopes this helps

Determine if each fraction is a terminating decimal or a repeating decimal. Write each fraction in the correct box.

Alja [10]

-7/9 is repeating
42/50 is terminating
-1/125 is terminating
-77/600 is repeating
179/200 is terminating
5/11 is terminating

The way to figure this out is just by dividing the Numerator (top number) by the denomiter (bottom number)
Example 5÷11=.45454545 repeating
