Answer 2

To evaluate the expression "(5целых 01/3-2) : 5/21," let's break it down step by step.

First, let's interpret the notation "(5целых 01/3-2)." It appears to be a mix of Russian and fractional notation. "5целых" in Russian means "5 whole" or "5 integer parts," and "01/3" represents the fraction 1/3. So, "(5целых 01/3-2)" can be understood as "5 whole parts plus 1/3 minus 2."

Next, let's simplify the expression:

5 whole parts plus 1/3 minus 2: = 5 + 1/3 - 2

Now, let's convert the mixed number into a fraction:

5 = 5/1

Now, we can combine the fractions:

5/1 + 1/3 - 2

To add or subtract fractions, we need a common denominator. The common denominator for 1 and 3 is 3:

5/1 + 1/3 - 2/1

To add or subtract fractions with the same denominator, we can directly operate on the numerators:

(5 + 1)/1 - 2/1 = 6/1 - 2/1 = (6 - 2)/1 = 4/1 = 4

Therefore, the expression "(5целых 01/3-2) : 5/21" simplifies to 4.
