Is there a shortcut to do this problem rather than going one after the other solving it ?
Even the "long way" is not too long
take 8 oz from A
divide by 5
2:6 (your left with 8:24 in A)
Now you have 6:42 in B
take 16 oz
thus divide by 3 take 2:14 from B and add to A
now you have 10:38 = 5/19
like high school chemistry again - do i miss those years!
