Answer :
2 3/10
5 1/10 - 2 8/10
You can’t subtract 1/10 by 8/10 so you regroup
The 5 turns into a 4 and 1/10 turns into 11/10
New equation would be 4 11/10 - 2 8/10 = 2 3/10
5 1/10 - 2 8/10
You can’t subtract 1/10 by 8/10 so you regroup
The 5 turns into a 4 and 1/10 turns into 11/10
New equation would be 4 11/10 - 2 8/10 = 2 3/10
