Question

(10/13 умнажаем 11/12) умнажаем (12/55 умнажаем 13/20)

Answer 1

( 10/13 * 11/12 ) * ( 12/55 * 13/20 ) = 55/78 * 39/275 = 1/10

Answer 2

Let's solve the expression step by step:

Step 1: Multiply (10/13) by (11/12) (10/13) * (11/12) = (110/156)

Step 2: Multiply (12/55) by (13/20) (12/55) * (13/20) = (156/1100)

Step 3: Multiply the results from Step 1 and Step 2 (110/156) * (156/1100) = (17160/1716000)

Now, let's simplify the final result: 17160/1716000 = 1/100

So, the final answer is 1/100.
