3 3/5 is mix number?
OpenStudy (anonymous):
yes it is
OpenStudy (anonymous):
than 3 3/5 is 18/5
OpenStudy (anonymous):
\[\frac{18}{5}-\frac{7}{10}\]
OpenStudy (anonymous):
ok i have that so far.

\[\frac{(18*2)-7}{10}\]
OpenStudy (anonymous):
\[\frac{36-7}{10}=\frac{29}{10}\]
OpenStudy (anonymous):
okay where did the 2 come from?
OpenStudy (anonymous):
denominator is 10
5*2=10
OpenStudy (anonymous):
never mind that the number for denominator right?

OpenStudy (anonymous):
okay got you. i have it im writin it down.
OpenStudy (anonymous):
denominator is 10
5*2=10
OpenStudy (anonymous):
k got that far.
OpenStudy (anonymous):

no not here,i mean you know conver to fraction
OpenStudy (anonymous):
yes i do
OpenStudy (anonymous):
good
OpenStudy (anonymous):
\[\frac{109}{6}-\frac{15}{2}\]r u ok from here?
OpenStudy (anonymous):
where did you get the 15 over 2 from?

7(1/2)=(7*2)+1=15
keep 2
OpenStudy (anonymous):
18(1/6)=(18*6)+1=109
keep 6
OpenStudy (anonymous):
it was not 2 its 7 1/12
OpenStudy (anonymous):
I ask u said yes
OpenStudy (anonymous):
on the bottom can u rewrite?

OpenStudy (anonymous):
im sorry i apologize.
OpenStudy (anonymous):
7(1/12) or 71/12
OpenStudy (anonymous):
18 1/6= 18(1/6)?
OpenStudy (anonymous):
yes thats right.
OpenStudy (anonymous):
7(1/12) ?

okay would you mind helping me .
OpenStudy (anonymous):
yes
OpenStudy (anonymous):
I will rewrite made sure it correct equation
OpenStudy (anonymous):
solve for n
1. n+1 3/8=2 1/4 2. 6 2/3=n-8 1/6 n okay thats fine. i apologize that i don't know how to help you understand
OpenStudy (anonymous):
u need help the mix number?

OpenStudy (anonymous):
do the make it a fraction?
OpenStudy (anonymous):
\[18\frac{1}{6}-7\frac{1}{12}\]?
OpenStudy (anonymous):
here it the problem cause thats not it.
solve for n
1. n+1 3/8=2 1/4 2. 6 2/3=n-8 1/6
OpenStudy (anonymous):
I still don't get
OpenStudy (anonymous):
n+1 time (3/8)=2 and 1/4?

OpenStudy (anonymous):
\[n+1\frac{3}{8}=2\frac{1}{4}\]?
OpenStudy (anonymous):
yes that is correct
OpenStudy (anonymous):
\[1\frac{3}{8}=(1*8)+3=\frac{11}{8}\]
OpenStudy (anonymous):
\[2\frac{1}{4}=(2*4)+1=\frac{9}{4}\]
OpenStudy (anonymous):
ok got that part so far
Join the QuestionCove community and study together with friends!
Sign Up
OpenStudy (anonymous):
\[n+\frac{11}{8}=\frac{9}{4}\]
OpenStudy (anonymous):
\[n=\frac{9}{4}-\frac{11}{8}\]
OpenStudy (anonymous):
denominator is 8, you need made 9/4 have the same 8 by time 2
OpenStudy (anonymous):
\[n=\frac{9*2}{4*2}-\frac{11}{8}=\frac{18}{8}-\frac{11}{8}\]
OpenStudy (anonymous):
k i got that so far

OpenStudy (anonymous):
\[n=\frac{7}{8}\]
OpenStudy (anonymous):
check : 7/8+11/8=18/8
= 9/4
OpenStudy (anonymous):
okay i have that. n when your done do you plug n chug
OpenStudy (anonymous):
and would u b able to help me with problem 2
OpenStudy (anonymous):
check:\[\frac{7}{8}+ \frac{11}{8}=\frac{18}{8}=\frac{9}{4}\]

2. 6 2/3=n-8 1/6
OpenStudy (anonymous):
\[6\frac{2}{3}=n-8\frac{1}{6}\]?
OpenStudy (anonymous):
yes correct
OpenStudy (anonymous):
u know conver fraction right ?
OpenStudy (anonymous):
its been a while. no

OpenStudy (anonymous):
\[6\frac{2}{3}=(6*3)+2=20\]\[6\frac{2}{3}=\frac{20}{3}\]
OpenStudy (anonymous):
\[8\frac{1}{6}=(8*6)+1=49\rightarrow \frac{49}{6}\]
OpenStudy (anonymous):
\[n=\frac{20}{3}+\frac{49}{6}\] denominator is 6 keep 49/6
20/3 time 2 , then denominator is the same 6
OpenStudy (anonymous):
\[n=\frac{20*2}{3*2}+\frac{49}{6}\]
OpenStudy (anonymous):
\[n=\frac{40+49}{6}=\frac{89}{6}\]

OpenStudy (anonymous):
I did check it correct
OpenStudy (anonymous):
is the answer 14 n 5/6
OpenStudy (anonymous):
yes the same
OpenStudy (anonymous):
\[14\frac{5}{6}=(14*6)+5=89 \rightarrow = \frac{89}{6}\]is you onver to fraction is the same
OpenStudy (anonymous):
k yeah i understand
