Use the four numbers in each line to make a fraction and an equivalent decimal - please show workings. thanks

?
- = ?.?

8 6 1 5
9 4 5 2
0 9 10 9
13 6 5 2
5 31 2 6
20 0 4 8
1 60 5 40

15/86 is the fraction then divide 15 by 86 and you get

0.1744 that would be one option for row one.
I'm not sure if you can make improper fractions but if you can it could also be 86/15 as a fraction then divide 86 by 15 5.7333 repeater. I am assuming you could arrange the numbers in any way for the fraction and then just divide the numerator by the denominator.

Good luck
