5. dan815

if you were to multiply the top and bottom of a fraction by the same number does that change anything?

6. Jravenv

Nope, It's still the same fraction, I believe.

7. dan815

yep

8. dan815

okay so lets multiply the right side by 2 top and bottom

9. dan815

what would it looks like then?

10. dan815

|dw:1433540546415:dw|

11. Jravenv

|dw:1433540636988:dw|

12. dan815

right

13. dan815

|dw:1433540688116:dw|

14. dan815

but llooks whats happened here

15. dan815

now the numerators are equal

16. dan815

and if these fractions are equal then that means the denominators must be equal tooo

17. dan815

for example if u have a fraction 20/50 = 20/X theres nothing else X can be but 50 too

18. dan815

so

19. dan815

20. dan815

|dw:1433540813925:dw|
