Answer 2

To simplify the expression, we need to convert all mixed numbers into improper fractions and perform the arithmetic operations according to the order of operations (PEMDAS).

2 целых 1/4 = 9/4 4 целых 5/6 = 29/6 3 целых 2/3 = 11/3 1 целое 1/4 = 5/4

So, the expression becomes:

(9/4 + 29/6) ÷ (11/3) - 5/4

To simplify the fractions, we need to find a common denominator.

The common denominator for 4, 6, and 3 is 12.

Multiplying the first term by 3/3 and the second term by 2/2, we get:

(27/12 + 58/12) ÷ (11/3) - 5/4

= (85/12) ÷ (11/3) - 5/4

To divide fractions, we can multiply the first fraction by the reciprocal of the second fraction:

(85/12) × (3/11) - 5/4

= 255/132 - 5/4

To subtract fractions, we need to find a common denominator:

(255/132) × (3/3) - (5/4) × (33/33)

= 765/396 - 165/132

= 215/132

Therefore, the simplified expression is 215/132.
