Answer. To verify that the decimals are lined up correctly, we must ensure that they are both lined up at the same point. The reason this is done is so that whole numbers will be subtracted from other whole numbers, not decimals.
Extra. Hope this helped, if it’s correct let me know so others can use it :)
Good luck :)
