(6*8)/*(8*2)
OpenStudy (anonymous):
i dont know how to simplify
OpenStudy (anonymous):
divide both numerator and denomitaor with 4 since 4 is the common number
OpenStudy (anonymous):
so 12/16 becomes 3/4
OpenStudy (asnaseer):
the rule to follow here is:\[\frac{a}{b}\div\frac{c}{d}=\frac{a}{b}\times\frac{d}{c}\]

so, in your case, we have:\[\frac{6}{8}\div\frac{2}{8}=\frac{6}{\cancel{8}}\times\frac{\cancel{8}}{2}\]
OpenStudy (asnaseer):
@haileyshay can you work it out now?
Parth (parthkohli):
I agree, but we can also do something like \[ {a \over c} \div {b \over d} = {a \div b \over c \div d} \Longrightarrow {6 \div 2 \over 8 \div 8}\] :)
OpenStudy (anonymous):
(6*8)/*(8*2) = 48/16 = 3
Parth (parthkohli):
That gives us the computation directly.

3x8
OpenStudy (asnaseer):
that was your first step?
OpenStudy (anonymous):
yes
OpenStudy (asnaseer):
try using this form:\[\frac{a}{b}\div\frac{c}{d}=\frac{a}{b}\times\frac{d}{c}\]now plug-in your values and see what you get.
OpenStudy (anonymous):
so 3 divided by 3

can you please write out your step fully using the formula I gave you above?
OpenStudy (asnaseer):
your question is: 3/5 divided by 3/8
so in this case:
a=3
b=5
c=3
d=8
plug those into the formula I gave you.
OpenStudy (anonymous):
i dont know how to make it look like a fraction on the computer
OpenStudy (asnaseer):
try using the Draw button and draw it out if that is easier.
OpenStudy (anonymous):
ok
