Answer:
How do I do this equation for my son 7.32 - 1.909
2 answers:
1. line up your numbers
2. notice how there is no number above the 9? Imagine a 0 there. You cannot subtract 9 from 0 so you would change the next number over to one less than before (2 to a 1) and carry a ten over to the 0 making it worth ten.
3. subtract 10 from 9 (getting 1)
4. subtract 1 from 0
5. you cannot take 3 away from 9 so you must once again carry a ten. Change the 7 to a 6 and change the 3 to a 13, then subtract 13 from 9
6. subtract 6 from 1
7. you should be left with 5,411. you are going to want to carry down the decimal to make it 5.411
8. you've successfully subtracted decimals
Hope this is helpful! Also this is in a step bye step form :)
