What happens when the X and Y are tripled;

When both X and Y are tripled, the new fraction is represented below:

When the numerator and denominator are divided by their common factor (3), the new fraction becomes


Compare the new fraction with the initial fraction; one would notice that they have the same value;
Hence, the fraction remains the same
Answer:
22%
Step-by-step explanation:
Divide 2,650 by 100:
2,650/100=26.5
Then divide 3233 by the dividend:
122=122%
Now you can see that there is a 22% percent increase over 100%, theefore making our answer 22%.

Answer:

Step-by-step explanation:
Previous concepts
The mean absolute deviation or MAD "is the average of the absolute deviations or the positive difference of the given data and that certain value (generally central values)". And is given by this formula:

Solution to the problem
Assuming the info from the picture. So then the data is this one:
66,69,70,70,71,72,72,72,73,73,74,75,75,75
So the first step is find the mean for the dataset with the following formula:

And if we replace the values we got:

And now we need to subtract for each value the mean like this:
Data 
66 5.929
69 2.929
70 1.929
70 1.929
71 0.929
72 0.0714
72 0.0714
72 0.0714
73 1.0714
73 1.0714
74 2.0714
75 3.0714
75 3.0714
75 3.0714
Now we need to add the deviations and divide by the the number of data values and we got:
