Question

without actually performing long division check these
ration will have terminating or hon terminating non terminating repeating decimal expansion
a) 6/15​

Answer 1

We can say

When the denominator is in the form of 2ᵇ × 5ⁿ then that rational number is terminating decimal

Where b and n are belongs to whole numbers

If the denominator is not in the form of 2ᵇ × 5ⁿ then it is non - terminating and non recurring decimal

6/15 = here 15 is not in the form of 2ᵇ × 5ⁿ So this is non terminating decimal
