I don't quite understand the ten strategy, or what EXACTLY you're asking. But, what you can do is when you add a one digit number plus a nine, just change the nine to a ten and subtract one. It is very easy. So, 7+10 equals 17, subtract one and you get 16 which is 7+9. It is always one less than anything plus 10.
The lower ratio would be bob and that dude need to slow down the hair stuff
10 to 8 ratio is about 8.00
7 to 6 ratio is about 9.00
im not to good at math so dubble cheek just in case hope i could help tho
rip my spelling
x+y=10
x+2y=14
x is common in both so u have to subtract the second one from 1st
x-x + y-2y = 10-14
-y = -4
y=4
which means bottle of water (y) = 4
and then substitute 4 in equation (x+y=10 or x+2y=10)
x + 4 = 10
x=6
If you add a zero to the end of .29 it becomes .290
So, the answer is .293 > .29
