Answer 2

To solve this expression, you should follow the order of operations, which is parentheses, exponents, multiplication and division (from left to right), and addition and subtraction (from left to right).

Let's break down the expression step by step:

1. First, evaluate the expressions inside the parentheses:

   • For the first set of parentheses: (0.216 / 0.15 + 2/3 : 4/15)

     Start with the division and then addition inside the parentheses:

     (0.216 / 0.15 + 2/3 : 4/15) = (1.44 + 0.133333...) ≈ 1.57333...

   • For the second set of parentheses: (196/225 - 7.7/24 + 3/4)

     Start with the subtraction, then addition:

     (196/225 - 7.7/24 + 3/4) = (0.871111... - 0.320833... + 0.75) ≈ 1.300277...

   • For the third set of parentheses: (0.695 / 1.39)

     Simply perform the division:

     (0.695 / 1.39) = 0.5

2. Now, sum all the results together:

   1.57333... + 1.300277... + 0.5

3. Add the results:

   ≈ 1.57333 + 1.300277 + 0.5 ≈ 3.373607

So, the final result is approximately 3.373607.
