@peachpi

4. anonymous

ok, so start the same way. What's the lcm/lcd of 8 and 12?

5. anonymous

The LCD of 8 & 12 is 24?

6. anonymous

yes. now choose what to multiply the fractions by. 8 * ___ = 24 12 * ___ = 24

7. anonymous

what are the blanks?

8. anonymous

the blanks are...

9. anonymous

3 and 2, right?

10. anonymous

right, so mulitply the first fraction by 3/3 and the second by 2/2

11. anonymous

yes that is what you have to multiply each of them by and the final answer would be...

12. anonymous

$\frac{ 7\times3 }{ 8\times3 }-\frac{ 5\times2 }{ 12\times2 }$

13. anonymous

21/24-10/24=11/24

14. anonymous

7*3=21 , 5*2=10 , 8*3=24 , and 12*2=24

15. anonymous

and I said NO direct answers PLZ!

16. anonymous

yes, try to get into the habit of keeping it all in the fraction, at least on paper

17. anonymous

sorry got a bit carried away

18. anonymous

20. anonymous

21. anonymous

23. anonymous

well you said to subtract the numerators

24. anonymous

25. anonymous

you have this, so now subtract 21 and 10 21/24-10/24 =

26. anonymous
