Пошаговое объяснение: удачи!!!

1)-3 2/8-16=-19 2/8

2)-7-(-4)+3=-7+4+3=-3+3=0

3)-2 4/15÷(-17)=​2 4/15:17=34/15:17=34/15:17/1=34/15*1/17=2/15

Answer 2

Let's solve each of these equations step by step:

1. -3 2/8 - 16: First, we'll convert the mixed number to an improper fraction: -3 2/8 = -3 (2/8) = -3 (1/4) = -3 * 1/4 = -3/4

Now, we can subtract 16 from it: -3/4 - 16 = -3/4 - 64/4 = (-3 - 64)/4 = -67/4

So, the answer is -67/4.

2. -7 - (-4) + 3: When you subtract a negative number, it's the same as adding the positive value. So, -7 - (-4) is the same as -7 + 4: -7 + 4 + 3 = -3 + 3 = 0

So, the answer is 0.

3. -2 4/15 ÷ (-17): First, convert the mixed number to an improper fraction: -2 4/15 = -2 (4/15) = -2 * (4/15) = -8/15

Now, divide by -17: (-8/15) ÷ (-17) = (-8/15) * (1/(-17)) = (8/15) * (1/17) = 8/255

So, the answer is 8/255, which can be simplified to 2/85 by dividing both the numerator and denominator by their greatest common divisor, which is 4.
