Question

write the following in decimal form and say what kind of expansion is 3 by 13​

Answer 1

Here, the numerator is 3 and denominator is 13.

Also,

for a terminating decimal expansion, the denominator must be expressed in the form of 2^m × 5^n

Here,

13 can't be expressed in the form of 2^m × 5^n , So it's a non-terminating number.

Decimal Expansion : 0.230769... ( repeating 230769 infinitely. )
