Question

Помогите пожалуйста решить пример(4.625 - 13/18 *9/26) : 9/4 =2.5:1.25:6.75) : 1целая 53/68 это числительВ знаменателе(1/2-0.375):0.125 + (5/6-7/12):(0.358-1.4796:13,7)Если можно по действиям.Решаем всем классом, у всех разные ответы :)Кто и где ошибается найти не можем

Answer 1

(1/2-0,375):0.125 + (5/6-7/12):(0,358-1,4796:13,7)=2

(4.625 - 13/18 *9/26) : 9/4 +2.5:1.25:6.75) : 1  53/68=1 7/27

Answer 2

Solving the Mathematical Expression Step by Step

Let's break down the given mathematical expression step by step.

1. Evaluate the Numerical Expression - First, we need to evaluate the numerical expression within the parentheses: \(4.625 - \frac{13}{18} \times \frac{9}{26}\). - Then, divide the result by \(9/4\).

2. Convert Mixed Number to Improper Fraction - The given mixed number \(1\frac{53}{68}\) needs to be converted to an improper fraction.

3. Simplify the Complex Fraction - Next, simplify the complex fraction \(\frac{1/2 - 0.375}{0.125}\).

4. Evaluate the Division - Finally, evaluate the expression \(\frac{5/6 - 7/12}{0.358 - \frac{1.4796}{13.7}}\).

Let's start by evaluating the numerical expression within the parentheses.

Numerical Expression Evaluation

The numerical expression within the parentheses is \(4.625 - \frac{13}{18} \times \frac{9}{26}\).

The result of this expression is then divided by \(9/4\).

Conversion of Mixed Number to Improper Fraction

The mixed number \(1\frac{53}{68}\) needs to be converted to an improper fraction.

Simplification of Complex Fraction

The complex fraction \(\frac{1/2 - 0.375}{0.125}\) needs to be simplified.

Evaluation of Division

Finally, we need to evaluate the expression \(\frac{5/6 - 7/12}{0.358 - \frac{1.4796}{13.7}}\).

Let's proceed with solving each step to find the solution.
