2. 4/11
3. 3/7

1/4*A = 1/7*B so 4/4*A = 4/7*B, ->3/7 of B left over

or if you want to make it into a word problem:

28oz of some liquid
4 size A test tubes = 7oz apiece
7 size B test tubes = 4oz apiece
(7-4)/7 = 3/7

just picked numbers to get 3/7

assume beaker holds 28 units and each size a holds 7 units, and each b holds 4 units.

the 7 from a into b leaves 3 units behind, since b take only take in 4 of the 7. left over is 3/7
