Answer 2

А) To add fractions, we need to find a common denominator. The common denominator for 12 and 4 is 12, so we can rewrite the fractions with this denominator:

5/12 + 3/4 = (5/12)(3/3) + (3/4)(3/3) = 15/36 + 9/36

Now that the fractions have the same denominator, we can add the numerators:

15/36 + 9/36 = (15 + 9)/36 = 24/36

The fraction 24/36 can be simplified by dividing both the numerator and the denominator by their greatest common divisor, which is 12:

24/36 = (24/12)/(36/12) = 2/3

So, 5/12 + 3/4 = 2/3.

Б) We have a mixed number and a whole number to add, so we need to convert the mixed number into an improper fraction before adding:

1 whole + 4/7 = (1*7/7) + 4/7 = 7/7 + 4/7 = 11/7

Now we can add the improper fraction and the whole number:

11/7 + 5 whole + 2/3 = 11/7 + (5*7/7) + 2/3 = 11/7 + 35/7 + 2/3

To add these fractions, we need to find a common denominator. The common denominator for 7 and 3 is 21, so we can rewrite the fractions with this denominator:

11/7 + 35/7 + 2/3 = (11/7)(3/3) + (35/7)(3/3) + (2/3)*(7/7) = 33/21 + 105/21 + 14/21

Now that the fractions have the same denominator, we can add the numerators:

33/21 + 105/21 + 14/21 = (33 + 105 + 14)/21 = 152/21

So, 1 whole + 4/7 + 5 whole + 2/3 = 152/21.

В) To add fractions, we need to find a common denominator. The common denominator for 4 and 6 is 12, so we can rewrite the fractions with this denominator:

1/4 + 5/6 = (1/4)(3/3) + (5/6)(2/2) = 3/12 + 10/12

Now that the fractions have the same denominator, we can add the numerators:

3/12 + 10/12 = (3 + 10)/12 = 13/12

The fraction 13/12 can be simplified by dividing both the numerator and the denominator by their greatest common divisor, which is 1:

13/12 = (13/1)/(12/1) = 13/12

So, 1/4 + 5/6 = 13/12.
