Answer 1

Ответ:

Пошаговое объяснение:

$\displaystyle \[\left( {14,7+23\frac{4}{5}} \right) \div 11=\left( {14,7+23,8} \right)\div 11=38,5 \div 11=\boxed{3,5}\]$

$\displaystyle \[\left( {61,68-4\frac{2}{{25}}} \right) \div 12=\left( {61,68-4,08}\right)\div 12=57,6\div 12=\boxed{4,8}\]$

Answer 2

To solve the given equations, let's break them down step by step:

Equation 1: (14,7 + 23,4/5) ÷ 11

Step 1: Divide 23.4 by 5 23.4 / 5 = 4.68

Step 2: Add 14.7 and the result from step 1 14.7 + 4.68 = 19.38

Step 3: Divide the result from step 2 by 11 19.38 / 11 ≈ 1.76

Therefore, the value of the first equation is approximately 1.76.

Equation 2: (61.68 - 4.2/25) ÷ 12

Step 1: Divide 4.2 by 25 4.2 / 25 = 0.168

Step 2: Subtract the result from step 1 from 61.68 61.68 - 0.168 = 61.512

Step 3: Divide the result from step 2 by 12 61.512 / 12 ≈ 5.126

Therefore, the value of the second equation is approximately 5.126.
