Answer 3

To solve the given expression step by step, we'll follow the order of operations: parentheses, exponents, multiplication and division (from left to right), and addition and subtraction (from left to right).

1. $2/20$ is equivalent to $0.1$.
2. $5+2$ is $7$.
3. $4/5$ is $0.8$.

Now, let's substitute these values into the original expression:

$1 + 0.1 + 65.2 - 35 + 7 + 0.8$

Now, we'll perform addition and subtraction from left to right:

$1.1 + 65.2 - 35 + 7 + 0.8$

$66.3 - 35 + 7 + 0.8$

$31.3 + 7 + 0.8$

$39.1$
