1) 53/8+47/8=100/8 или ,если перевести в обыкновенную дробь то 12 целых 4/8= 12целых 1/2.

Ответ:12 1/2 или 100/8

2)81/6 — 75/6= 6/6=1. или этот же пример перевести в обыкновенную дробь

13 3/6 — 12 3/6=1

Answer 2

To solve the given expressions, let's perform the calculations step by step:

1. Addition: 5 3/8 + 4 7/8

To add these mixed numbers, we first need to convert them into improper fractions:

5 3/8 = (8 * 5 + 3)/8 = 43/8 4 7/8 = (8 * 4 + 7)/8 = 39/8

Now, we can add the fractions:

43/8 + 39/8 = (43 + 39)/8 = 82/8

The sum 82/8 can be simplified:

82/8 = (2 * 41)/(2 * 4) = 41/4

So, 5 3/8 + 4 7/8 equals 41/4.

2. Subtraction: 81/6 - 7 5/6

Again, let's convert the mixed number into an improper fraction:

7 5/6 = (6 * 7 + 5)/6 = 47/6

Now, we can subtract the fractions:

81/6 - 47/6 = (81 - 47)/6 = 34/6

The fraction 34/6 can be simplified:

34/6 = (2 * 17)/(2 * 3) = 17/3

So, 81/6 - 7 5/6 equals 17/3.
