Answer:
Improper: 2 42/9 proper: 6 6/9
Step-by-step explanation:
2 7/9 x 2/3
find the common denominator which is 9 so now we have,
2 7/9 x 2/9
find the numerator which is,
2 7/9 x 6/9
multiply
2 42/9
This fraction is improper so lets make it proper,
42 goes into 9 four times
so we have,
6/9 + 2 + 4
final answer,
6 6/9
I am not 100 percent sure but i think you multiply and the answer is 7.75 if not then try to divid how you get 7.75 is you make 3/4 into a decimal and that becomes 0.75 them multiply by 10 and get 7.75
Answer:
Here is the complete question attached with.
The mean score would decrease more than the median score.
Step-by-step explanation:
The numbers for which we have to find the mean and median are:

Here the mean, 
Median,
as median is the middle term if the observations are arranged in ascending order.
Now as the question says that we have to add a zero to see its effect.
So adding a zero we have
Mean 
Median
,as number of observations is even terms so we will add two middle numbers and divide it with
.
So we can conclude that the mean is having more variation than the median.
Mean shows as variation of
where as Median shows a variation of
only.
So our final answer is option D that is "The mean score would decrease more than the median score."
