Answer 1

1) -7 1/2 : (-5) = -15/2 · (-1/5) = (3·1)/(2·1) = 3/2 = 1 целая 1/2

3) -11 1/5 : (-6) = -56/5 · (-1/6) = 56/30 = 28/15 = 1 целая 13/15

5) -7 3/5 : (-4) = -38/5 · (-1/4) = 38/20 = 19/10 = 1 целая 9/10

Answer 2

It appears that you have provided three expressions, each consisting of a fraction and a colon followed by a negative number. These expressions seem to be in the form of "fraction : negative number." To solve them, you can simply perform the division.

Let's calculate each expression:

1. -7 1/2 : (-5) This means you need to divide -7 1/2 by -5. -7 1/2 ÷ (-5) = 15/2 ÷ (-5) = -15/10 = -3/2.

2. -11 1/5 : (-6) This means you need to divide -11 1/5 by -6. -11 1/5 ÷ (-6) = 56/5 ÷ (-6) = -(56/5) ÷ 6 = -(56/5) × (1/6) = -(56/30) = -(28/15).

3. -7 3/5 : (-4) This means you need to divide -7 3/5 by -4. -7 3/5 ÷ (-4) = 43/5 ÷ (-4) = -(43/5) ÷ 4 = -(43/5) × (1/4) = -(43/20).

So, the results of the three expressions are:

1. -7 1/2 : (-5) = -3/2
2. -11 1/5 : (-6) = -(28/15)
3. -7 3/5 : (-4) = -(43/20)
