Answer 1

Ответ:

Пошаговое объяснение:

2 4/13:(-15/26)=30/13*(-26/15)=-4

3,75*2=7,5

-4-7,5=-11,5

Answer 2

Let's break down the expression step by step:

1. First, calculate the division: 2 ÷ (4/13) = 2 * (13/4) = 26/4 = 13/2.

2. Next, subtract the result from step 1 from (-15/26): (-15/26) - (13/2).

3. To subtract fractions, you need a common denominator, which in this case is 2. So, convert (-15/26) to a fraction with a denominator of 2: (-15/26) = (-15/26) * (1/2) = (-15/52).

4. Now, subtract the fractions: (-15/52) - (13/2).

To subtract fractions with different denominators, you need a common denominator. In this case, the common denominator is 52, so you need to adjust the fractions accordingly:

(-15/52) - (13/2) = (-15/52) - (338/52).

5. Subtract the numerators: (-15 - 338) / 52 = (-353) / 52.

Now, let's simplify the fraction:

(-353) / 52 can be simplified by dividing both the numerator and denominator by their greatest common divisor, which is 1:

(-353/1) / (52/1) = -353/52.

So, the result of the expression is -353/52.

6. Finally, multiply this result by 3.75:

-353/52 * 3.75 = (-353 * 3.75) / 52.

Now, calculate the numerator:

(-353 * 3.75) = -1323.75.

So, the final result is:

-1323.75 / 52.
