@peachpi

4. anonymous

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

5. rainbow_rocks03

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. rainbow_rocks03

the blanks are...

9. rainbow_rocks03

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. rainbow_rocks03

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

15. rainbow_rocks03

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
