please do the both question for me which are in image.​

Answer 1

Answer:

Step-by-step explanation:

1. Option (c) 0.401400140001 because this a non terminating and non repeating decimal.

2. Let x = 0.3333333.........

10x = 3.333333.........

So, (10x-x) = (0.333......)-(3.333.......)

=>9x = 3

=>x = 3/9 .......(1)

Let y = 0.4444444.........

10y = 4.444444..........

So, (10y-y) = (4.444.......)-(0.444.........)

=>9y = 4

=>y = 4/9 ........(2)

Adding (1) and (2)

x+y

= 3/9+4/9

= 7/9

Hence, the answer is option (b) 7/9
