Question

3 3/4*(4 1/2: 6 3/4) срочнооо!!!!

Answer 1

Ответ:

2 1/2 = 2,5

Пошаговое объяснение:

3 3/4*(4 1/2: 6 3/4) = 15/4 * (9/2 : 27/4) = 15/4 * (9/2 * 4/27) = 15/4 * 2/3 = 5/2 = 2 1/2 = 2,5

Answer 2

Переводим смешанные дроби в неправильные:

$\frac{15}{4} * (\frac{9}{2} : \frac{27}{4}) = 2,5$

1) $\frac{9}{2} : \frac{27}{4} = \frac{9}{2} * \frac{4}{27} = \frac{2}{3}$

2) $\frac{15}{4} * \frac{2}{3} = \frac{5}{2} = 2,5$

Answer 3

To solve the expression 3 3/4 * (4 1/2 : 6 3/4), you should follow the order of operations, which is often remembered with the acronym PEMDAS:

P - Parentheses E - Exponents MD - Multiplication and Division (from left to right) AS - Addition and Subtraction (from left to right)

Let's solve it step-by-step:

Step 1: Convert mixed numbers to improper fractions. 3 3/4 = (43 + 3)/4 = 15/4 4 1/2 = (24 + 1)/2 = 9/2 6 3/4 = (4*6 + 3)/4 = 27/4

Step 2: Perform the division inside the parentheses. (9/2) : (27/4) = (9/2) * (4/27) = 36/54

Step 3: Simplify the fraction obtained from the division. 36/54 = 2/3

Step 4: Now, perform the multiplication. 15/4 * 2/3 = (15 * 2) / (4 * 3) = 30/12

Step 5: Simplify the final fraction. 30/12 = 5/2 = 2 1/2

The result of the expression is 2 1/2.
