Question

write whether the rational no 7/15 will have a terminating decimal expansion or a non terminating repeating decimal expensions

Answer 1

Answer: No Terminating.

Step-by-step explanation: Numbers in the form p/q where q ≠ 0 and (p,q) are integers will only have terminating decimal if q = 2ᵃ x 5ᵇ where a and b are some integers.

E.g.: 5/100

Answer 2

Answer:

Step-by-step explanation:

7/15which is in p/q form

Therefore 7/15 is a rational number

Now q =15=2X3X5

So 2^mx5^nis not in the form

7/15is non terminating decimal expansion
