Question

2) -1 3/11 × (-2 2/21)​

Answer 1

Ответ:

2 2/3

Пошаговое объяснение:

-1 3/11 × (-2 2/21)​=1 3/11*2 2/21=14/11*44/3=8/3=2 3/3

Answer 2

To multiply these mixed numbers, we first need to convert them into improper fractions:

-1 3/11 = -(11/11 + 3/11) = -14/11 -2 2/21 = -(21/21 + 2/21) = -23/21

Now we can multiply them:

-14/11 × -23/21 = (14/11) × (23/21) = (2 × 7) / (11 × 3) × (23 / (3 × 7)) = 14/33 × 23/7

We can simplify the fractions before multiplying them:

14/33 = 2/3 and 23/7 cannot be simplified further.

Now we can multiply:

2/3 × 23/7 = (2 × 23) / (3 × 7) = 46/21

Therefore, -1 3/11 × (-2 2/21) = 46/21.
