Which of the following rational number can be represented as terminating and which as non terminating decimals? give the answer without actual dividing
Let, N is Numerator and D is Denominator.
I believe the value of N ÷ D will NOT be a repeating decimal if and only if D is any of the following
Otherwise, if none of the two rules above hold true, then the positive whole numbers N and D will divide into repeating decimal.
8 has only one prime factor whic is 2.
so it is a terminating decimal
15 has prime 3 factor 5 which is neither 2 nor 5 .so it is a repeating decimal
