Answer 2

To solve the expression, let's convert the mixed number "7 целых 1/4" into an improper fraction first.

7 целых 1/4 = 7 + 1/4 = 28/4 + 1/4 = 29/4

Now, the expression becomes:

5/6 + 29/4 - 1/72

To add fractions, they need to have the same denominator. The common denominator for 6 and 4 is 12.

Convert the fractions to have a common denominator of 12:

(5/6) * (2/2) = 10/12 (29/4) * (3/3) = 87/12

Now, the expression becomes:

10/12 + 87/12 - 1/72

Now, all the fractions have the same denominator. We can add them together:

(10/12) + (87/12) - (1/72) = 97/12 - 1/72

To subtract fractions, they also need to have the same denominator. The common denominator for 12 and 72 is 72.

Convert the fractions to have a common denominator of 72:

(97/12) * (6/6) = 582/72

Now, the expression becomes:

582/72 - 1/72

Finally, we can subtract the fractions:

582/72 - 1/72 = (582 - 1) / 72 = 581/72

So, the simplified answer is 581/72.
