Question

Solve for n round to the tenths place 14/21.2= n\15

Answer 1

Well.... first lets break this problem up. and work on the left side first 
soo we solve this ↓
14/21.2 = 0.66
now lets plug in our values. The left side will just be replaced by 0.66
Soooo
0.66 = n/15 
so this means we do the opposite on both sides of what n and 15 are doing
In this case they are dividing so yes we are doing the opposite by multiply.
sooooo
0.66 = n/15
 ×15 = x 15 they cancel out on the right hand side and lets solver for the left side.
0.66 x 15 = 9.9 
so that means 
n = 9.9
or we could round it and just say 10
n = 10 
hope this helps:P
