can someone help me please... simplify. show your work please 5 1/3+ (-3 9/18)

OpenStudy (anonymous):

I would first make them improper fractions.

OpenStudy (moka414):

the parenthis?

OpenStudy (anonymous):

you can remove the parentheses and make it 5 1/3 - 3 9/18.

OpenStudy (moka414):

oh okay

OpenStudy (anonymous):

So next you make them improper fraction by multiplying 5*3 and then adding 1 to make 16/3. Try the other fraction.

OpenStudy (moka414):

ok

OpenStudy (moka414):

im writing it down :)

OpenStudy (moka414):

what throws me off is that the minus sign like -3

OpenStudy (anonymous):

so what you do is ignore the minus sign.... and do the same so multiply 3*18 and add 9.... Next, put that over 18. So the answer would be.....Try it.

OpenStudy (moka414):

okay

OpenStudy (moka414):

63/18?

OpenStudy (anonymous):

Yes!

OpenStudy (anonymous):

So now you have 16/3 - 63/18. So you can multiply the first fraction by 6 to the numerator and the denominator. Try it.

OpenStudy (moka414):

okay

OpenStudy (moka414):

like 16 x 6 and 3 x 6?

OpenStudy (anonymous):

Yes

OpenStudy (moka414):

96/18

OpenStudy (anonymous):

Yes! Now you have 96/18 - 63/18. The next step would be to simplify it by subtracting them.

OpenStudy (moka414):

96-63=33 and 18-18=0

OpenStudy (moka414):

like that or am I mistaken

OpenStudy (moka414):

I think is 33/18 1.833 no?

OpenStudy (anonymous):

Yes! The answer would be 33/18. Nice Job!

OpenStudy (moka414):

thanks
