Question

Add.

1\2+3\4+1\2

Answer 1

1/2+1/2=1,1+3/4=7/4

Answer 2

thats wrong thats not one of the awnsers

Answer 3

Hi, Alex!
Glad to be of help here, but have to admit that your posting is just a bit hard for me to read. By 1\2+3\4+1\2 , do you mean
\[\frac{ 1 }{ 2 }+\frac{ 3 }{ 4 }+\frac{ 1 }{ 2 }?\]

Answer 4

1+3/4

Answer 5

yea how do you do that

Answer 6

robtobey really knows his stuff, Alex, so if he didn't come up with the proper answer, it was because of ambiguity in the problem statement.

Answer 7

he was wrong it is 1 and 7\4

Answer 8

find a common denominator. In this case it would be 4. So1/2 would become 2/4. so 2/4 + 2/4 + 3/4= 7/4 or you could simplify it to 1 and 3/4. Another way to do it is 1/2 + 1/2 = 1 so 1+3/4= 1 and 3/4

Answer 9

rotobey suggesting re-arranging the addends like this:\[\frac{ 1 }{2 }+\frac{ 1 }{ 2 }+\]\[\frac{ 3 }{ 4 }\] and that adds up to 1 + 3/4 and that is absolutely identical to \[1\frac{ 3 }{ 4 }\]

Answer 10

oh it is nvm

Answer 11

So Rob was NOT at all wrong. Sometimes we need to look for equivalent forms; 1 + 3/4 will equal 1.75, 1 3/4 and the like.

Answer 12

why did he say 1 and 7\4

Answer 13

Mind giving robtobey a medal? He was first to come up with an entirely correct answer.

Answer 14

i gave Princesslord1000 because she was more explanitory

Answer 15

Well, perhaps you had a point there. Note:\[1+\frac{ 3 }{ 4 }=\frac{ 4 }{ 4 }+\frac{ 3 }{ 4 }=\frac{ \frac{ }{ 7 } }{ 4 }\]

Answer 16

That last fraction is a 7/4.

Answer 17

but he did say 1 and 3\4

Answer 18

i ment did not

Answer 19

Where?

Rob first typed 1/2 = 1/2 = 1, which is true and appropriate.

What he typed next would have been easier to read had he used a new line.

1/2 + 3/4 + 1/2 does equal 1 + 3/4.

1=4/4,

so 1+3/4 = 4/4 + 3/4 = 7/4.

Let's focus on your ability to recognize equivalent expressions.

7/4 = 1.75 = 1 3/4 = 1 + 0.75 (and so on). All have the same value, and the better you are at recognizing this, the better you'll do in math.
