espex · Answer

You recall how to calculate efficiency?

anonymous · Answer

yea but I don't know how to find these

espex · Answer

Each of these is a ratio of $\frac{output}{input}$, so just use the same process we did on the other questions.

anonymous · Answer

are these vthe outpu

espex · Answer

They are a ratio, output/input.

espex · Answer

Let's take "A" for example. This is saying that you have "1 unit" of output for every "2 unit" of input.

anonymous · Answer

espex · Answer

Yes, but do not forget that you are representing them as % so you multiply your decimal by 100.
