Can u tell me how to solve this promblem 4/7 plus 3/7

The answer to your question is:  Yes, I can.

Although you haven't asked me to actually show you how, I'm already here
so I might as well just go on through it.

Before we tackle that math problem, I want to discuss a couple of other
different ones, and I want you to solve both of them.

Problem #1:     4 (cows) + 3 (cows)
Can you solve it ?
Did you say " 7 (cows) " ?
Nice work.

Problem #2:     4 (blue bicycles) + 3 ( blue bicycles)
This one is a little harder.
Can you solve it on your own ?
What's that ?  Did you say " 7 (blue bicycles) " ?
Excellent !

I think you're ready for the original problem now:

       4 (sevenths) + 3 (sevenths) = ?

I hope you said " 7 (sevenths) " .
You did ?  Terriffic !
That's the correct solution . . . . . ⁷/₇.

Teachers usually want to see fractions simplified.  That doesn't
change the answer, it's just a neater way to write it.

Any fraction that has the same number on top and bottom is always the same as ' 1 '.

⁷/₇ = 1 , so if you see the answer to this one in a book, it'll say ' 1 '.
