Пошаговое объяснение:

4/5+6/7=28/35+30/35=58/35=1 23/35

8/11-4/11=4/11

Answer 3

To solve these expressions, you can follow these steps:

1. Add 4/5 and 6/7:

   4/5 + 6/7

To add these fractions, you need to find a common denominator. The least common multiple of 5 and 7 is 35. So, you can rewrite both fractions with a common denominator of 35:

(4/5) * (7/7) + (6/7) * (5/5) = 28/35 + 30/35

Now that the fractions have the same denominator, you can add them:

28/35 + 30/35 = (28 + 30)/35 = 58/35

2. Subtract 4/11 from 8/11:

   8/11 - 4/11

Since both fractions have the same denominator (11), you can directly subtract them:

(8/11) - (4/11) = 4/11

So, the final results are:

4/5 + 6/7 = 58/35 8/11 - 4/11 = 4/11
