Answer 1

Given is:-

by multiplying and dividing the given fraction with 1000 we get

we can clearly see that the denominatior is greater then the numerator.

Therefore the result must be less then 1.

FIrst we put decimal and follow the rules of division to get the desired result.

After dividing we get

Thus it is repeated over and over again

Thus the result to proper number of significant figures is

  (The significant digits in numerator is 3 and the significant digits in denominator is 2. therefore the result must contain 2 significant digits)

Hence the given division to the proper number of significant figures is
