Question

0.7, 0.07, 0.007, ... find Sn of G.P​

Answer 1

Answer:

7/9

Step-by-step explanation:

0.7, 0.07, 0.007, ...

7/10  , 7 /100  , 7/1000 ,.........................

= 7/10  , 7/10²  . 7/10³ ,.............

this is an infinite GP

with a  = 7/10

r = Common ration  = 1/10

Sum of infinite GP = a/(1 - r)

= (7/10) /(1 - 1/10)

= (7/10)/(9/10)

= 7/9
