If 1 euro is the same as \$1.30, and 1 franc is the same as \$1.10, what is the ratio of euros to francs?

I'm not sure why BC tells me to make both euros and francs equal to \$1.30, why not just make them equal to \$1 instead?

I'm sure there are many ways to solve these types of ratio problems, BC just decided to make them equal to \$1.30, but you could make them equal to \$1.10 or \$1 even, I think \$1 would just be an extra step, one that you don't need or else you'll be wasting time on the real thing. Hope this makes sense.

You can make \$1 your baseline for comparison, but that would require an additional step in the whole process like artist2022 stated. The fastest way would be to equalize based on \$1.30 or \$1.10 since that is already one of your given conversion rates.
