Answer 1

Answer:

non-  terminating

Step-by-step explanation:

1/2+2/3+3/4+4/5=

1/60(30+40+45+48)=

163/60= 2 43/60

• 43/60= 0.71 (6) = non-terminating

2 43/60= 2. 716666666666666..

• Example: 0.5, 2.456, 123.456, etc. are all examples of terminating decimals.

• Non terminating decimals: Non terminating decimals are those which keep on continuing after decimal point (i.e. they go on forever). They don't come to end or if they do it is after a long interval.

115.2

it is non terminating
