@ArkGoLucky

2. ArkGoLucky Group Title

um I don't think this is possible because the numerator of the first fraction is not changed so it can't equal the second fraction. ever

3. ArkGoLucky Group Title

4 does not equal 7

4. KE8717504 Group Title

it dosent' have a answer box for not a answer

5. KE8717504 Group Title

@jim_thompson5910

6. KE8717504 Group Title

I have no idea either

7. ArkGoLucky Group Title

oh wait nvm, there is an answer. The number just has to be a fraction

8. KE8717504 Group Title

ok.

9. ArkGoLucky Group Title

Is there a box for a fraction?

10. KE8717504 Group Title

yea

11. ArkGoLucky Group Title

okay cool

12. KE8717504 Group Title

do u know it? lol

13. ArkGoLucky Group Title

okay got

14. ArkGoLucky Group Title

it

15. ArkGoLucky Group Title

so here's what you do so make an equation say x is the number you're looking for try to think of a way you can make an equation using x

16. ArkGoLucky Group Title

ask if you need help

17. ArkGoLucky Group Title

I'll give you a hint use 4x

18. KE8717504 Group Title

ok so what do i do now with the 4x?

19. KE8717504 Group Title

is the answer going to be 2? @ArkGoLucky

20. ArkGoLucky Group Title

not quite. I'll just show you the equation. So you know that the number x, when multiplied by the numerator(4) then added to the denominator(9) equals 7/4 That means 4/9+4x=7/4

21. KE8717504 Group Title

so 7/4 is the answer or do i solve that?

22. ArkGoLucky Group Title

no, now you solve for x, which is the number you're looking for

23. KE8717504 Group Title

i got 47/144?

24. KE8717504 Group Title

is that right or wrong?

25. ArkGoLucky Group Title

almost

26. ArkGoLucky Group Title

the numerator is right except it's a negative and the denominator is wrong

27. KE8717504 Group Title

how did i get the denominator wrong?

28. ArkGoLucky Group Title

did you solve x in$\frac{ 4 }{ 9+4x }=\frac{ 7 }{ 4 }$

29. KE8717504 Group Title

yea and i got that big fraction

30. ArkGoLucky Group Title

try plugging in your answer into that equation

31. ArkGoLucky Group Title

okay I'll show you how to solve for x multiply both sides of the equation by the common denominator. In this case, it is (4)(9+4x) this is to rid of the fractions

32. ArkGoLucky Group Title

when you do this, you get 16=7(9+4x) I'm sure you can solve for x now
