Answer 1

ж) 3/4 + 5/18 = 27/36 + 10/36 = 37/36 = 1 целая 1/36
з) 2/26 + 3/39 = 1/13 + 1/13 = 2/13
и) 7/34 + 5/51 = 21/102 + 10/102 = 31/102

Answer 2

Solution for the Given Expressions

Let's solve the given expressions step by step.

a) 3/4 + 5/18: To add these fractions, we need to find a common denominator. The least common multiple of 4 and 18 is 36. So, we can rewrite the fractions with a common denominator of 36: - 3/4 = 27/36 - 5/18 = 10/36

Now, we can add the fractions: - 27/36 + 10/36 = 37/36

So, 3/4 + 5/18 = 37/36.

b) 2/26 + 3/39: Similarly, to add these fractions, we need to find a common denominator. The least common multiple of 26 and 39 is 78. So, we can rewrite the fractions with a common denominator of 78: - 2/26 = 6/78 - 3/39 = 6/78

Now, we can add the fractions: - 6/78 + 6/78 = 12/78

Simplifying the result, we get: - 12/78 = 2/13

So, 2/26 + 3/39 = 2/13.

c) 7/34 + 5/51: Once again, to add these fractions, we need to find a common denominator. The least common multiple of 34 and 51 is 102. So, we can rewrite the fractions with a common denominator of 102: - 7/34 = 21/102 - 5/51 = 10/102

Now, we can add the fractions: - 21/102 + 10/102 = 31/102

So, 7/34 + 5/51 = 31/102.

Final Results:

- 3/4 + 5/18 = 37/36 - 2/26 + 3/39 = 2/13 - 7/34 + 5/51 = 31/102
