What you are essentially doing is:
\[\frac{6}{7} \times \frac{1}{3}\]
Do you know how to do this?
OpenStudy (anonymous):
Not really
OpenStudy (anonymous):
To multiply 2 fractions together all you do is multiply the numerators together and the denominators together.
So what you ahve to do is:
\[\frac{6\times1}{7\times3}\]
Understand?
OpenStudy (anonymous):
Yes thanks

6/21
OpenStudy (anonymous):
Excellent, can you simplify this fraction at all?
OpenStudy (anonymous):
3/21?
OpenStudy (anonymous):
Not quite, remember what you do to the top you have to do to the bottom as well if you want to keep the fraction the same.
Hint: Both the numerator and denominator are multiples of 3.

1/7?

That would be right for 3/21, you looked at the wrong fraction.
What we have is 6/21 :) Try again.

3/7

?
OpenStudy (anonymous):
No, we divide the top and bottom by 3. So we have:
\[\frac{6}{21}=\frac{6\div3}{21\div3}=\frac{2}{7}\]
