subtracting 3 - 4/5?

-------------------------------------------------------

answers:
say: 3 - (4/5)
= ((3×5) - 4 )/5
= 11/5
-
MICHAEL K say: 2 1/5.
-
David say: The difference is 2 and 1/5 or 2.2
-
Como say: :-
Method 1
By inspection, answer is 2 1/5

Method 2
15/5 - 4/5 = 11/5 = 2 1/5
-
RR say: You could write 3/1 - 4/5 and find a common denominator (5)
15/5 - 4/5
= 11/5
= 2 1/5

or you could do it in your head:
3 - 1 = 2
2 + 1/5 = 2 1/5
-
ted s say: 2 + 5/5 - 4/5 = 2 1/5
-
Krishnamurthy say: 3 - 4/5
= 2 1/5
= 2.2
-
ET say: 4/5 = .8
3 - .8 = 2.2
-
Jason Chow say: In order to add or subtract fractions you need to make sure that both numbers share a common denominator. In this case, it could be 5.
Give 3 a denominator of 5 by multiplying it by 5 and putting it over 5.
3 --> 15/5
Now you can subtract 3 and 4/5.
15/5 - 4/5 = 11/5
[When you subtract fractions, the denominator stays the same while you subtract as normal for the numerator]
