Пошаговое объяснение:

45/13+16/13-33/18= 45+16/13-11/6= 61/13-11/6=366-143/78= 223/78

Answer 2

To perform the arithmetic calculation, let's convert the mixed numbers to improper fractions and then simplify the expression:

4 5/13 + 1 6/13 - 3 3/18

First, let's convert the mixed numbers to improper fractions: 4 5/13 = (4 * 13 + 5) / 13 = 57/13 1 6/13 = (1 * 13 + 6) / 13 = 19/13 3 3/18 = (3 * 18 + 3) / 18 = 57/18

Now we have: 57/13 + 19/13 - 57/18

To add or subtract fractions, we need to find a common denominator. In this case, the common denominator is 13 * 18 = 234.

Rewriting the fractions with the common denominator: (57/13) * (18/18) + (19/13) * (18/18) - (57/18) * (13/13)

Now we can combine the fractions: (57 * 18 + 19 * 18 - 57 * 13) / (13 * 18)

Performing the calculations: (1026 + 342 - 741) / 234 = 627/234

The fraction 627/234 cannot be simplified further.

However, we can express it as a mixed number: 627 divided by 234 equals 2 with a remainder of 159.

So the final result is: 2 159/234
