Answer 1

Ответ:

Думаю так, 1) -3/8+5/12= 3/8+5/12 нужно найти общий знаменатель, общий знаменатель 24= 9/24+10/24=19/24

2) -12/9-21/6= 12/9-21/6= нужно найти общий знаменатель, общий знаменатель 18= 24/18-63/18=-39/18=-13/6= 2целых 1

Ответ:

-3 25/72

Пошаговое объяснение:

-3/8+5/12 -1 2/9-2 1/6 → приведём все дроби к общему знаменателю 72:

-27/72 + 30/72 - 1 16/72 - 2 12/72 = 30/72 - 27/72 - (1 16/72 + 2 12/72) =

3/72 - 3 28/72 = -3 25/72

Answer 3

To solve the expression -3/8 + 5/12 - 1 + 2/9 - 2 + 1/6, we can follow these steps:

Step 1: Find a common denominator for the fractions involved. In this case, the common denominator is 24 because it is divisible by 8, 12, 9, and 6.

Step 2: Convert each fraction to have the common denominator of 24.

- -3/8 becomes -9/24 - 5/12 remains as 5/12 - 1 becomes 24/24 - 2/9 becomes 8/24 - 2 becomes 48/24 - 1/6 becomes 4/24

Step 3: Add or subtract the fractions.

- -9/24 + 5/12 - 24/24 + 8/24 - 48/24 + 4/24

Step 4: Combine the numerators and keep the common denominator.

- (-9 + 5 - 24 + 8 - 48 + 4)/24

Step 5: Simplify the numerator.

- (-74)/24

Step 6: Simplify the fraction.

- -74/24

Step 7: Reduce the fraction to its simplest form.

- -37/12

Therefore, the solution to the expression -3/8 + 5/12 - 1 + 2/9 - 2 + 1/6 is -37/12.
