Question

1/4x + 2/3 < 3/4

I got 1/3 when I multiplied the whole thing by 12.
But when I added, subtracted and used the common denominators method, I came to
3/12x<1/12
How do you solve that? Please explain.

I also have another question, if you were to graph an equality that was an improper fraction, would you graph it converting to a mixed number or just using that improper fraction to graph?

Answer 1

When you multiply by 12... you should have gotten

3x + 8 < 9

Answer 2

Yes I did, but the final answer I got was 1/3.

Answer 3

Oh, 1/3 is correct.

Answer 4

x < 1/3

Answer 5

Can you tell me how you would do it 3/12x<1/12 that way? How do you divide that?

Answer 6

So how would you read that? 1/12 divided by 3/12 right?

Because if you had

4x < 8

It would turn into 8 divided 4...

Answer 7

When dealing with fractions what ever you are dividing by you must flip... then multiply

Answer 8

1/12 * 12/3

Answer 9

What does that equal @one2345

Answer 10

Oh, I see. Isn't it 2?

Answer 11

12/36 = 1/3

Answer 12

Oops, I multiplied the numbers across by accident... Thanks!

And can you please answer the last question?

Answer 13

I suppose you would change that to a Mixed number since it would be better to see where it should go.

Answer 14

Okay, thank you sooooo much!

Answer 15

You are welcome. :)
