Question

(1/2-3/4):(-2 3/4)=???

Answer 1

Ответ:

1/11

Пошаговое объяснение:

1/2-3/4=-1/4

-2 3/4=-11/4

-(1/4)/(-(11/4))=(1/4)×(4/11)=1/11

Answer 2

To solve this expression, you need to 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)

Let's proceed with the calculations:

Step 1: Perform the division inside the parentheses first. (1/2 - 3/4) = (2/4 - 3/4) = -1/4

Step 2: Now, divide -1/4 by -2 3/4.

To divide a fraction by a mixed number, you can convert the mixed number to an improper fraction first:

-2 3/4 = -2 + 3/4 = -8/4 + 3/4 = -5/4

Now, the division becomes:

(-1/4) / (-5/4)

To divide fractions, you invert the divisor (the number you're dividing by) and multiply:

(-1/4) * (-4/5) = (1/4) * (4/5) = 1/5

So, the result of the expression is 1/5.
