0,8 1,7 2,6 3,5 these are the numbers that add up to eight. Then I tested every single one as the following

1,2 3,4 8,0 6,7 5,9 this is a possible solution so that 0,8 is a number that can be in it

0,3 1,7 2,5 4,9 8,6 this is another possible solution so 1,7 could be possible

but if we use 2,6 we have to use 0,3 to add up for 3 therefore we cant get the one for 7s because that the numbers that adds up to seven which are 1,6 2,5 3,4 0,7 all the digits here has already been used up

3,5 is another possible solution 1,2 0,7 3,6 4,9 and 8,6 the possible ones for eight is 0,8 1,7 and 3,5.
