Answer 2

Answer: Our required answer is $8.\bar{3}$

Step-by-step explanation:

Since we have given that

$3.\bar{5}+4.\bar{7}$

So, it can be written as

$3.\bar{5}=3.555555555.....\\\\and\\\\4.\bar{7}=4.7777777777....$

On adding both the terms:

$3.5555555555+4.7777777777=8.333333333333\\\\=8.\bar{3}$

Hence, our required answer is $8.\bar{3}$
