It's not so easy for my math

Alice would be rewarded with 10/1015 of the reward fund for 9.985 STEEM and Bob would be rewarded with 5/1015 of the reward fund for 4.926 STEEM.

For me Alice's figure should be 9.852 instead of 9.985.

And here:

The pool of recent rshares contains 1000 rshares, and the reward fund holds 100.000 STEEM

I need to adjust the figure of 100.000 STEEM to 1000.000 STEEM to understand all the calculations done in hypothetical examples here.

I wonder how everyone else here is understanding these figures. Am I missing something?
