Answer 2

Д) Calculating 21/22*(22/23*24/25)*23/24: First, let's simplify the expression inside the parentheses: 22/23*24/25. This can be calculated as (22*24)/(23*25) = 528/575.

Now we can rewrite the original expression with the simplified part: 21/22*(528/575)*23/24. We can multiply the fractions in the numerator and denominator: (21*528*23)/(22*575*24) = 264264/74400.

So, the value of the expression 21/22*(22/23*24/25)*23/24 is 264264/74400.

е) Calculating 32/33*52/53*(53/52*33/34): First, let's simplify the expression inside the parentheses: 53/52*33/34. This can be calculated as (53*33)/(52*34) = 1749/1768.

Now we can rewrite the original expression with the simplified part: 32/33*52/53*(1749/1768). We can multiply the fractions in the numerator and denominator: (32*52*1749)/(33*53*1768) = 30528/31359.

So, the value of the expression 32/33*52/53*(53/52*33/34) is 30528/31359.
