where did you get 2

5. mayankdevnani

by divide 4 by 8 and then multiply by 1=2

6. mayankdevnani

7. Claire4christ

4/8=0.5

8. mayankdevnani

@Claire4christ You need to learn fraction operations ( add/ subtract/ multiply/ divide) to keep the result precisely.

11. Claire4christ

@Chlorophyll i learn all the that i just forgat how to do it

12. Chlorophyll

Do you know what the common denominator?

13. Claire4christ

its the buttom number

14. Chlorophyll

Yes, denom = 8

15. Chlorophyll

What number to multiply 4 to get 8?

16. Claire4christ

1/4+3/8

17. Claire4christ

4x2=8

18. Chlorophyll

=> ( 1/4) * 2 = 2/8 Then after you have the common denom, now you can add 2 fractions together.

19. Chlorophyll

That's where the "2" come from!

20. Claire4christ

ok now i got it

These are basic 4th grade math, you should be able to review it on your own :/
