Answer=18%
177/150=1.18
1.18=118%
118%-100%=18%
___________________________
another way to solve the equation...
150 177
_____=_____
100% x
Cross Multiply
150x=17700
divide both sides by 150
x=118%
118%-100%=18%
1-9 = 9 digits
10-99 = 180 digits
So if we continue the pattern to 99, there are 189 digits, and the last 5 digits would be 79899. Counting backwards: 189th = 9, 188th = 9, 187th = 8, 186th = 9, 185th = 7.
The 185th digit is 7.
