Answer 1

13/18*36/13=1/2
13/18:5/18=2целых 3/5
3 13/18-15/18=2 16/18
11/18*2=1 2/9
13/18+5/6=28/18

Answer 2

To solve the expression 13/18 * 36/13 + 13/18 : 5/18 + 3 + 13/18 - 15/18 + 1 + 1/18 * 2 + 2/19 + 13/18 + 5/6 + 13/18 + 5/27 + 13/18 - 5/11, we can follow the order of operations (PEMDAS/BODMAS).

Let's break this down step by step:

Step 1: Multiplication and Division First, let's simplify the multiplication and division parts of the expression:

13/18 * 36/13 = (13 * 36) / (18 * 13) = 468 / 234 = 2

13/18 : 5/18 = (13/18) / (5/18) = (13/18) * (18/5) = (13 * 18) / (18 * 5) = 13 / 5 = 2.6

1/18 * 2 = 2/18 = 1/9

2/19 remains the same

Step 2: Addition and Subtraction Now, let's simplify the addition and subtraction parts of the expression:

2 + 2.6 + 3 + 1 + 2/19 + 13/18 + 5/6 + 13/18 + 5/27 + 13/18 - 5/11

To add and subtract fractions, we need to find a common denominator. In this case, the common denominator is 18. Let's convert all the fractions to have a denominator of 18:

2 + 2.6 + 3 +
