Since dividing by a fraction is multiplying by the reciprocal;
It's Keep Change Flip
So before you have:
15 divided by 9/2
we keep the 15
change the sign

15 multiplied by 2/9
so now you can solve as normal
Answer:
we know that mean of the data set is
Sum of all terms / total no. of terms
mean = 120+145+130+80+95+100+340+n / 8
140 = 1010+n / 8
140*8 = 1010 + n
1120 = 1010 + n
1120 - 1010 = n
110 = n
therefore the value of n should be 110
