When you add and subtract fractions, you need to use their common denominators.
1 3/4 + 4/5 = 1 15/20 + 16/20 = 1 31/20 = 2 11/20
Use the same method to solve your subtraction problem. We'll be glad to check your answer.
Then does 3 1/8 - 1 1/2 = 2 3/8??
No. Sorry.
3 1/8 - 1 4/8 = 2 9/8 - 1 4/8 = ?
Ohhhhhh ok now i understand it you have to borrow from the whole number right?
Right! :-)
Ohh ok thank you so much for your help =]
You're very welcome. :-)
