Question

Without actually performing the long division,state whether 77/210 will have a terminating decimal expansion or non-terminating repeating decimal expansion.Give reason​

Answer 1

Answer:

no it is not

Explanation:

77/210.

simplify it by dividing nominator and denominator both by 7 we get 11/30  

Factorize the denominator we get  

30 = 2 x 3 x 5  

Denominator has 3 also in denominator so denominator is not in form of 2n x 5n  

Hence it is non terminating

Answer 2

Answer

non terminating REPEATING DECIMAL EXPANSION
