Find the sum.

OpenStudy (anonymous):

\[7\frac{ 3 }{ 4 } + ( -8 \frac{ 1 }{ 2 })\]

OpenStudy (anonymous):

Can someone show me step by step how to do this? I'd appreciate it..

OpenStudy (anonymous):

@rizwan_uet do you know how to do this

OpenStudy (anonymous):

the question is not in proper format

OpenStudy (anonymous):

Why's that?

OpenStudy (anonymous):

there are alot of brackets and slashes i cant figure out the exact problem

OpenStudy (anonymous):

@rizwan_uet it's #5

OpenStudy (anonymous):

for the first fraction multiply 4 with 7 and 3 to it for second fraction mutiply 8 with 2 and add 1 to it thus we get 31/4 + (-17/2) can you do it further??

OpenStudy (anonymous):

You transformed them into improper fractions... I'm honestly not sure why /.\ but do I have to find a common denominator or something before I can add them?

OpenStudy (anonymous):

4 is for the coomon denmnator

OpenStudy (anonymous):

yes 4 is the common denominator

OpenStudy (anonymous):

Would that be 31/4 + (-34/4)

OpenStudy (anonymous):

yup

OpenStudy (anonymous):

What do I do afterwards? Is the answer -3/4

OpenStudy (anonymous):

yuu got it!

OpenStudy (anonymous):

Oooh thank you both...
