Answer 2

2 1/3:(5/8-8/3)-2*1 3/7 =34/7

Answer 3

Let's break down the expression step by step:

1. First, simplify the fractions within the parentheses:

   5/8 - 8/3 = (15/24) - (64/24) = (15 - 64)/24 = (-49/24)

2. Next, calculate 2 * 1 3/7:

   2 * 1 3/7 = 2 * (7/7 + 3/7) = 2 * (10/7) = (20/7)

3. Now, you have the expression: 2 1/3 : (-49/24) - (20/7)

4. To simplify further, convert 2 1/3 to an improper fraction:

   2 1/3 = (3 * 2 + 1)/3 = (7/3)

5. Rewrite the expression with the fractions in a common denominator:

   (7/3) : (-49/24) - (20/7)

6. To divide fractions, multiply by the reciprocal of the second fraction:

   (7/3) * (-24/49) - (20/7)

7. Calculate the first part:

   (7/3) * (-24/49) = (-168/147) = (-56/49)

8. Now, you have:

   (-56/49) - (20/7)

9. To subtract these fractions, find a common denominator:

   (-56/49) = (-8/7)

10. Now, you have:

    (-8/7) - (20/7)

11. Subtract the fractions:

    (-8/7) - (20/7) = (-8 - 20)/7 = (-28/7) = -4

So, the value of the expression 2 1/3 : (5/8 - 8/3) - 2 * 1 3/7 is -4.
