wait why is 6/5 an option? i got something bigger than 1.5 so that tripped me up for a sec

6/5 is what you'd get if you messed up the ratio direction, common trap

confused on the '2-dozen' part at first, but once you know that's 24 it's straightforward.

is this really sub-505? felt easy compared to some of the ratio ones i've done

What this question tests

Your ability to convert between fractions, ratios, and decimals and to reason proportionally.

Cross-multiplying incorrectly or mixing up the ratio parts — a part:part ratio is not a fraction of the whole.
