Question

The weight of an object on the moon is 1/6 its weight on earth. write 1/6 as a decimal

Answer 1

Point six repeatedly so 0.16666666666... so just put a bar over the six 

Answer 2

Answer:

Weight of the object on the moon

      $=\frac{1}{6} \times \text{Weight of an object on the earth}$

If in a fraction,that is rational number, denominator has term other than

                                   $2^a , \text{or},5^b,\text{or} ,2^a \times 5^b}$

then the decimal expansion will be non terminating repeating.

 $\rightarrow\frac{1}{6}=0.1666.....\\\\=0.167\text{approx}$
