Question

-11/36+(-17/24)=7/10+(-13/15)=-2/9-5/18=-1/3-(-5/6)=​

Answer 1

Ответ:

Пошаговое объяснение:

1) = -22/72 - 51/72 = -73/72 = -1 1/72

2) = 21/30 - 26/30 = -5/30 = -1/6

3) = -4/18 - 5/18 = -9/18 = -1/2

4) = -2/6 + 5/6 = 3/6 = 1/2

Answer 2

Пошаговое объяснение:

1) ((-11)*2+(-17)×3)÷72=-73/72=-1 1/72

2) (7×3+(-13)+2)/30=-5/30=-1/6

3) ((-2)×2-5)/18=-9/18=-1/2

4) ((-1)×2-(-5))/6=3/6=1/2

Answer 3

Let's simplify each of these expressions step by step:

1. -11/36 + (-17/24): To add fractions with different denominators, you need to find a common denominator. In this case, the common denominator is 72. -11/36 * 2/2 = -22/72 -17/24 * 3/3 = -51/72

   Now, you can add them: (-22/72) + (-51/72) = -73/72

2. 7/10 + (-13/15): To add these fractions, find a common denominator, which is 30. 7/10 * 3/3 = 21/30 -13/15 * 2/2 = -26/30

   Now, you can add them: (21/30) + (-26/30) = (21 - 26)/30 = -5/30

   Simplify further by dividing both the numerator and denominator by their greatest common divisor, which is 5: (-5/5) / (30/5) = -1/6

3. -2/9 - 5/18: To subtract fractions, find a common denominator, which is 18. -2/9 * 2/2 = -4/18 5/18 is already in the correct form.

   Now, you can subtract them: (-4/18) - (5/18) = (-4 - 5)/18 = -9/18

   Simplify further by dividing both the numerator and denominator by their greatest common divisor, which is 9: (-9/9) / (18/9) = -1/2

4. -1/3 - (-5/6): To subtract fractions, change the subtraction of a negative fraction into addition: -1/3 + 5/6

   To add these fractions, find a common denominator, which is 6. -1/3 * 2/2 = -2/6 5/6 is already in the correct form.

   Now, you can add them: (-2/6) + (5/6) = (-2 + 5)/6 = 3/6

   Simplify further by dividing both the numerator and denominator by their greatest common divisor, which is 3: (3/3) / (6/3) = 1/2

So, the results are: -11/36 + (-17/24) = -73/72 7/10 + (-13/15) = -1/6 -2/9 - 5/18 = -1/2 -1/3 - (-5/6) = 1/2
