This is definitely a test-day trap
thanks a lot
thanks, this one was pretty quick once I set up the ratio
same, i almost picked 5/6 out of habit though lol
wait why isnt it just 5/6? the ratio says five rock for every six jazz so i thought rock was 5/6
the ratio compares rock to jazz, not rock to total. you have to add the parts together to get the total songs
ahh i see, so the 6 is jazz not the whole thing. that trips me up every time
easy points, just remember rock/total not rock/jazz
What it tests
Your ability to convert between fractions, ratios, and decimals and to reason proportionally.
Common trap
Cross-multiplying incorrectly or mixing up the ratio parts — a part:part ratio is not a fraction of the whole.
