Question

13/51 : (4/17-20/51)

Answer 1

4/17-20/51=12/51-20/51=-8/51
13/51:(-8/51)=13/51*(-51/8)=-13/8=-1 5/8

Answer 2

To solve the expression, follow the order of operations (PEMDAS/BODMAS):

1. Perform the operations inside the parentheses first: (4/17 - 20/51) = (204/867 - 340/867) = (-136/867) = -136/867

2. Then, perform the division: 13/51 ÷ (-136/867)

When dividing fractions, you can multiply the first fraction by the reciprocal of the second fraction:

13/51 × (-867/136)

3. Now, perform the multiplication:

   (13 × -867) / (51 × 136) = -11271 / 6948

The final result is approximately:

-11271 / 6948 ≈ -1.622
