Step-by-step explanation:

1/5=0.2

Answer 2

Answer:

B. 1/5

Step-by-step explanation:

A terminating decimal, true to its name, is a decimal that has an end.

So, we need to figure out which one has an end.

1/3 is a pretty famous non-terminating decimal, 0.333333333333333333333 etc, so A is not our answer

1/5 works! 1/5 is 0.2 so B is our answer

1/7 is 0.142857 etc etc so C is not our answer

1/9 is another slightly famous non-terminating decimal, 0.1111111111111111 (2/9 is 0.222 etc, 3/9 is 0.33333 etc, and it goes up to 9/9 which is 1!) so D is not our answer
