According to vulgar fractions;

If given 0.1666 = (16 - 1)/90 = 15/90 = 1/6.

But here 0.1667 so can we consider it as 0.1666.

@Rakesh:
0.1667 is equivalent to (16-1)/90(by RECURRING DECIMAL) we get 1/6. 5/6 is equal to (83-8)/90.

Am I right?

0.1667 can be treated as 0.16666 since they are asking for approximate values.

@Ashique.

If we subtract 10x = 1.667 from x = 0.1667 then we get 9x = 1. 5003
