Division by rational (decimal) number meaning
When I say, that I exchanged 42 CZK into 1,5 euro. Why do I get the rate for one euro by dividing?
1) How do you explain this division in words. Like when you say when doing integer division, that you divide 10 cookies to 2 people, so one get 5. That type of style.
2) Does division always gives back an average rate per 1 unit of somethings?
3) the same for mean average, I bought 100 units of something for 2500 unit of any currency. 2500/100 = 25 per one (25/1).
How do you explain this in words too, please. Something like you want to distribute 2500 into 100 equal parts and the answer is the units per one?
Thanks, All I care is the problems being said in words, meaning of division rational number by rational number, in this case in its decimal form
