please Tell answer ​

Answer 1

Answer:

Hey ! Here's your answer:

Step-by-step explanation:

a. 158 / (2² * 5² * 13) is non-terminating as other than 2 and 5, there's a 13 as well. Terminating decimals should have only 2 and 5 as prime factors.

b. 123/120

= 41/40 = 41 / (2³ * 5), which is terminating.
