Question

-14/5 × 25/28+(-36/37):(-6/37)/-дробь.​

Answer 1

Ответ:

$- \frac{14}{5} \times \frac{25}{28} + ( - \frac{36}{37} ) \div ( - \frac{6}{37} )$

$- \frac{14}{5} \times \frac{25}{28} = - \frac{14 \times 25}{5 \times 28} = - \frac{5}{2}$

$- \frac{36}{37} \div ( - \frac{6}{37} ) = \frac{36 \times 37}{37 \times 6} = 6$

$- \frac{5}{2} + 6 = \frac{7}{2}$

Answer 2

To solve the expression, let's follow the order of operations (PEMDAS/BODMAS):

1. Parentheses/Brackets
2. Exponents/Orders
3. Multiplication and Division (from left to right)
4. Addition and Subtraction (from left to right)

The given expression is:

(-14/5) × (25/28) + (-36/37) ÷ (-6/37) / -дробь

Note: The term "-дробь" seems to be in Russian, but it is not clear what specific number or expression it represents. If you provide the value of "-дробь," I can include it in the calculation. For now, I'll assume that "-дробь" means "-1/2."

First, let's simplify the division:

(-14/5) × (25/28) + (-36/37) ÷ (-6/37) / (-1/2)

Next, let's proceed with the multiplication:

(-14/5) × (25/28) + (-36/37) ÷ (-3/37)

Now, let's deal with the division:

(-14/5) × (25/28) - (36/37) × (-37/3)

Now, let's multiply:

-14/5 × 25/28 - 36/3

Now, we'll calculate the fractions:

(-14 * 25) / (5 * 28) - 12

(-350) / 140 - 12

-2.5 - 12

Finally, subtract:

-14.5

So, the result of the expression is -14.5.
