8 + (-13/5) + (4/3)=
\[8 + (-\frac{ 13 }{ 5 }) + (\frac{ 4 }{ 3 })=\]
get the LCD.. :)
How do you do that with a problem like this?
haha.. i don't know .. but I know how to solve. LOL
Can you show me how to solve it then, please?
do you know what is LCD?
Least common difference?
no.. least common denominator..
Oh
so, do you know that??
I think I do. It has been awhile since I've done it though.
okay.. so get the LCD. try it first on your own. :)
15?
yes.. :) then divide and multiply it to the numbers..
8+(-39/15) + (20/15)
no.. wrong. :) include 8 in dividing and multiplying.. :)
101/15
yes.. :) you're right.. :) you can translate that in mixed fractions or in decimal form, if you don't want the improper fraction to be your final answer,.. :)
Would I divide 15 into 101 to make it a mixed fraction?
\[8 + \frac{(-13)}{5} +\frac{ 4}{3}=8 - \frac{13}{5} +\frac{ 4}{3}=8 +\frac{ 4}{3}- \frac{13}{5} \] \[=8 +\frac{ 4 \times 5 - 13 \times 3}{3 \times 5} =8 +\frac{ 20 - 39}{15}=8 +\frac{ - 19}{15}\] \[=\frac{ 8 \times 15- 19}{15}=\frac{ 120- 19}{15}=\frac{ 101}{15}\]
6 11/15
thanks
