Question

5+2 1\3/(-9,8)-5/(-21)=

Answer 1

5 + 2 1/3 : (-9,8) - 5 : (-21) = 5

1) 2 1/3 : (-9,8) = 7/3 : (-98/10) = 7/3 · (-10/98) = -(1·10)/(3·14) = -10/42 = -5/21

2) 5 : (-21) = -5/21

3) 5 + (-5/21) - (-5/21) = 5 - 5/21 + 5/21 = 5

Answer 3

Let's break down the expression step by step:

1. 5 + 2 1/3: First, we need to convert the mixed fraction to an improper fraction: 2 1/3 = (2 * 3 + 1) / 3 = 7 / 3 Now, add 5 to this fraction: 5 + 7/3 = (15/3) + (7/3) = 22/3

2. (-9,8): I'm not sure what you mean by "(-9,8)". If you intended this to be a subtraction, please provide the correct format.

3. -5 / (-21): Simply divide -5 by -21: -5 / -21 = 5/21

Now let's put it all together:

(22/3) / (-9,8) - (5/21)

Since the format of the subtraction part is not clear, please provide the correct format for that part of the expression so I can continue with the calculation.
