In 1992, a scoop of gelato could be purchased in Italy for 1200 lire. The same gelato would have cost $1.50 in the U.S. At the equivalent exchange rate between the lire and the dollar, how many dollars would be equivalent to $$1,000,000$$ lire?

In order to get to 1000000 lire, we must multiply the entire ratio by 1000000/1200=833 1/3. So we have: 1.5:1200 =1.5*833 1/3 : 1200 * 833 1/3 = 1250:1000000. So$1250 is equivalent to 1000000 lire.

In 1992, a scoop of gelato could be purchased in Italy for 1200 lire. The same gelato would have cost $1.50 in the U.S. At the equivalent exchange rate between the lire and the dollar, how many dollars would be equivalent to 1,000,000 lire? I'll set this up as a proportion. 1.50 is to 1,200 as X is to 1,000,000 Substitute a dividing line for "is to" 1.50 X and substitute an equal sign for "as" –––––– = ––––––––– 1,200 1,000,000 Now do the arithmetic. We called it "cross multiplying" when I was in school, a couple hundred years ago (1.50) • (1,000,000) = (1,200) • X Divide both sides by 1,200 and put the X on the left. You can leave (1.50) • (1,000,000) it on the right if you want to, I just like X = –––––––––––––––––– it better on the left 1,200 Breaking out the old calculator because I'm to lazy to do the arithmetic manually and find X = 1,250 dollars, equivalent to a million lire .

The other side of that coin is that some people give too little explanation, or none at all.
