Question

here the answer is 3/4 i need step by step explenation​

Answer 1

Answer:

1//2 + 1/6 + 1/18 + 1/24 + 1/72 . . .     (since series involves multiplying previous denominators by 3)

Now, since it is difficult to add all the way to infinity, and also since the numbers progressively become smaller in size, we tend to ignore those and consider only the first 5 of the series.

1/2 + 1/6 + 1/18 + 1/24 + 1/72 will approximately equal 3/4

Thus 3/4 is the answer.

I hope this helps you . . . please comment if further doubt.
