Question

check whether 17/21 is a rational number with terminating decimal part or not ​

Answer 1

Answer:

here it is

Step-by-step explanation:

denominator is 21

if we prime factorise it then 21 = 3*7

for a terminating decimal, denominator should have 2^n*5^m form (2 power n

multiplied by 5 power m form)

therefore, 17/21 is not terminating

if you actually divide it then answer comes 0.80952

therefore, it is not terminating
