In a few exercises, I've needed to get the union or intersection of fractions or percentages.
I'm not confident I fully understand.
If I need the intersection of $A = 0.75$ and $ B = 0.5$, do I just take the larger number and subtract the smaller number? So the $ A \cap B$ would be $0.25$? And the union would just be the larger number i.e. $A$ or $0.75$?
And I suppose the same must be true for fractions.
Is this correct? Seems too easy.
