Question

Describe the steps you would use to subtract 7.6 from 20.39

Answer 1

Okay Here is my help (:

So you would write it like this
20.39
- 7.60
you always want to make sure that the decimals are lined up !

and its okay to ad a zero to the end to make it more visable.

20.39
- 7.60
_____
so first step is 9-0 which is just 9

you would put the 9 at the bottom
20.39
- 7.60
_____
9

next you would subtract 3-6 which doent work so you need to borrow rom the next number to the left so you need to make the 0 in the 20 a 10 and make the 2 a 1 in the 20 so then it would look like this
1 10
(2 0) . 3 9
- 7 . 6 0
_____
9
then you make the 3 a 13 (:
1 10 13
(2 0) . 3 9
- 7 . 6 0
_____
9
so now whats 13 minus 6 thats 7 so now it would look like this
1 10 13
(2 0) . 3 9
- 7 . 6 0
_____
7 9
then subratc 7 from the 10 which is 3

1 10 13
(2 0) . 3 9
- 7 . 6 0
_____
3 . 7 9
make sure to bring the decimal down
and then cary the 1 back down because theres nothing to subract from 1

so your answer is 13.79 (: i hope this helps i know it an be confusing sometimes (: Don't worry jsut try to think it through
