The answer is A and D
In answer choice A the fractions are 3/6 and 4/6. In the original equation in fractions are 1/2 and 2/3. The equivalent fraction to 1/2 is 3/6 because 1x3=3 and 2x3=6, therefore 3/6 is equivalent. The equivalent fraction to 2/3 is 4/6 because 2x2=4 and 3x3=6, therefore 4/6 is equivalent.
In answer choice D the fractions are 9/18 and 12/18. In the original equation in fractions are 1/2 and 2/3. The equivalent fraction to 1/2 is 9/18 because 1x9=9 and 2x9=18, therefore 9/18 is equivalent. The equivalent fraction to 2/3 is 12/18 because 2x6=12 and 3x6=18, therefore 12/18 is equivalent.
Hope this helps :D

23.714285714286
Step-by-step
The mean absolute deviation of a set of data is the average distance between each data value and the mean.
1. Find the mean.
2. Find the distance between each data value and the mean. That is, find the absolute value of the difference between each data value and the mean.
3. Find the average of those differences.
Find the cost of 1 kilogram, by dividing the cost of 2 by 2:
4.50 / 2 = $2.25 per kilogram.
Now multiply the cost of 1 by 3:
2.25 x 3 = $6.75 for 3 kilograms.
Step-by-step explanation:
So this identity is true.
