what??
OpenStudy (anonymous):
here is what you do, in case this number is not familiar to you
write
\[x=.2666..\]
\[10x=2.6666...\]
\[9x=10x-x=2.4\]
\[x=\frac{2.4}{9}=\frac{24}{90}=\frac{4}{15}\]
OpenStudy (anonymous):
you can check that it is right
use a calculator

yes its right - thanx satellite - i'd done these before but my memory failed me !
OpenStudy (fellowroot):
2.666-0.2666 is not 2.4, its 2.3994
OpenStudy (anonymous):
but 4/15 is not in the choices..
OpenStudy (cwrw238):
its not 2.666 - its 2.6666.......
so 2.4 is correct
OpenStudy (cwrw238):
what are your choices?

i dun get it.. the choices are
12/45, 26/90, 28/90
OpenStudy (cwrw238):
those are incorrect
use your calculator - you'll find that none of them is right
OpenStudy (cwrw238):
hold on - sorry 12/45 is the correct choice
- this simplifies to 4/15
