Question

2,4:(1,5* 3 1\3 - 1 4\5)

Answer 1

Ответ:

$\frac{12}{5} \div ( \frac{3}{2} \times 3 \times \frac{1}{3} - \frac{14}{5} )$

$\frac{12}{5} \div ( \frac{3}{2} - \frac{14}{5} )$

$\frac{12}{5} \div ( - \frac{13}{10}$

$- \frac{12}{5} \times \frac{10}{13}$

$- \frac{24}{13}$

$- 1 \frac{1}{13}$

Answer 2

It looks like you have a mathematical expression that needs to be solved. Let's break it down step by step:

2,4: (1,5 * 3 1\3 - 1 4\5)

I'm assuming the comma (,) is meant to represent a decimal point, so the expression becomes:

2.4: (1.5 * 3 1\3 - 1 4\5)

Now, let's simplify the expression inside the parentheses first:

3 1\3 is a mixed number and can be written as an improper fraction: 3 1\3 = 3 + 1\3 = 3 + 1/3 = 10/3

1 4\5 is also a mixed number and can be written as an improper fraction: 1 4\5 = 1 + 4\5 = 1 + 4/5 = 9/5

So the expression inside the parentheses becomes:

1.5 * (10/3 - 9/5)

Next, let's find a common denominator for the fractions inside the parentheses, which is 15:

10/3 = (10/3) * (5/5) = 50/15 9/5 = (9/5) * (3/3) = 27/15

Now the expression becomes:

1.5 * (50/15 - 27/15)

Now we can subtract the fractions inside the parentheses:

(50/15 - 27/15) = (50 - 27)/15 = 23/15

Finally, we can multiply 1.5 by the result:

1.5 * (23/15)

To multiply a decimal by a fraction, we can convert the decimal to a fraction with a denominator of 1, so 1.5 can be written as 3/2.

Now the expression becomes:

(3/2) * (23/15)

To multiply fractions, we multiply the numerators together and the denominators together:

(3 * 23) / (2 * 15) = 69 / 30

Now we can simplify the fraction:

69/30 = (3 * 23)/(2 * 15) = 69/30 = (3 * 23)/(2 * 15) = 69/30 = 23/10

So the simplified result of the expression is:

2.4: 2.3
