1)-9/11+(-4 3/11)= 2)-3/17+(-11/34)= 3)-7/12+(-8 1/6)*​

Answer 1

Ответ:

Пошаговое объяснение:

1)-9/11+(-4 3/11)= -9/11 - 4 3/11 = -13 12/11 = -14 1/11

2)-3/17+(-11/34)= -6/34 - 11/34 = -17/34 = -1/2

3)-7/12+(-8 1/6) = -7/12 - 8 2/12 = -8 9/12 = -8 3/4

Answer 2

1. To add these two mixed numbers, we first need to convert them into improper fractions:

-9/11 + (-4 3/11) = -9/11 + (-47/11) = (-9 - 47) / 11 = -56/11

Therefore, -9/11 + (-4 3/11) = -56/11.

2. We can add these two fractions directly because they have the same denominator:

-3/17 + (-11/34) = (-6/34) + (-11/34) = -17/34

Therefore, -3/17 + (-11/34) = -17/34.

3. To add these mixed numbers, we first need to convert them into improper fractions:

-7/12 + (-8 1/6) = -7/12 + (-49/6) = (-76 - 492) / (12*6) = -97/72

Therefore, -7/12 + (-8 1/6) = -97/72.
