Negative reciprocals of each other
The are 9 pieces of data in the set so we have:
(27+32+14+19+24+26+22+32+29)/9 = 25
25 is the mean of the set of data.
8/m-9=6/m-8
Move -9 to the other side. Sign changes from -9 to +9.
8/m-9+9=6/m-8+9
8/m=6/m+1
Move +6m to the other side. Sign changes from +6m to -6m.
8/m-6/m=6/m-6/m+1
2m could also equal to : 1/2m
1/2m=1
Multiply by 2/1 for 1/2m and 1.
1/2(2/1)m=2/1(1)
Cross out 2 and 2, divide by 2. Cross out 1 and 1, divide by 1.
m=2
Answer: m=2
