Answer 1

Ответ:

  $\frac{59}{12}$  or  $4\frac{11}{12}$  or  $4,9$  

Объяснение:

  $4 : 4\frac{4}{5}+ 2\frac{2}{7}*5\frac{1}{4}-7\frac{11}{12}=4 : \frac{24}{5}+\frac{16}{7}*\frac{21}{4}-\frac{95}{12}=\frac{5}{6}+ 12 - \frac{95}{12}= \frac{59}{12}=> 4\frac{11}{12}=> 4,9$

Answer 2

It looks like you've provided a mathematical expression that combines whole numbers and fractions. Let's break it down step by step:

1. 4:4 is a ratio notation. It can also be written as 1:1, which means the ratio is 1 to 1, or simply 1.

2. 4/5 + 2 is a addition of a fraction and a whole number. First, let's simplify the fraction: 4/5.

   The expression becomes: (4/5) + 2

3. 2/7 • 5 is a multiplication of a fraction and a whole number. First, let's simplify the fraction: 2/7.

   The expression becomes: (2/7) * 5

4. 1/4 - 7 11/12 is a subtraction of a fraction and a mixed number. First, let's convert the mixed number to an improper fraction:

   7 11/12 = (7 * 12 + 11) / 12 = 95 / 12

   The expression becomes: (1/4) - (95/12)
