Answer 2

Let's break down the expression step by step:

1. 4 + (2/15) + (31/9) - (6/5) = (4 * 9/9) + (2/15) + (31/9) - (6/5) = (36/9) + (2/15) + (31/9) - (6/5)

2. Now, let's find a common denominator for the fractions in the expression, which is 45:

(36/9) + (2/15) + (31/9) - (6/5) = (36/9) * (5/5) + (2/15) * (3/3) + (31/9) * (5/5) - (6/5) * (9/9) = (180/45) + (6/45) + (155/45) - (54/45)

3. Now, add and subtract the fractions:

(180/45) + (6/45) + (155/45) - (54/45) = (180 + 6 + 155 - 54) / 45 = 287 / 45

4. Finally, multiply the result by 0.9:

(287/45) * 0.9 = (287 * 0.9) / 45 = 258.3 / 45

To simplify this fraction, you can divide both the numerator and the denominator by their greatest common divisor (GCD), which is 3:

(258.3 / 3) / (45 / 3) = 86.1 / 15

So, the final result of the expression is 86.1 / 15, which is approximately equal to 5.74 when rounded to two decimal places.
