Answer 3

To solve the expression, we'll follow the order of operations, which states that multiplication and division should be performed before addition and subtraction.

Let's start by calculating the products first:

9 1/6 * 7,8 = (9 + 1/6) * 7,8 = (55/6) * 7,8 = (55/6) * (78/10) = (55 * 78) / (6 * 10) = 4290 / 60 = 71.5

9 1/6 * 4,2 = (9 + 1/6) * 4,2 = (55/6) * 4,2 = (55/6) * (42/10) = (55 * 42) / (6 * 10) = 2310 / 60 = 38.5

Now, let's add the results:

71.5 + 38.5 = 110

Therefore, 9 1/6 * 7,8 + 9 1/6 * 4,2 equals 110.
