Which of the following is equivalent to \[6\frac{ 3 }{ 7 } \div 12\]
Choices:
a. \[6\frac{ 1 }{ 28 }\]
b. \[1\frac{ 13 }{15 }\]
c. \[\frac{ 15 }{ 28 }\]
d. \[2\frac{ 1 }{ 28 }\]

Here is a trick that I learned to help with these.
We have
\[6\frac{3}{7}\div 12\]
We can do this to make the fraction proper.
\[\frac{(7\times 6) + 3}{7} = x\]
\[x\times \frac{1}{12} = final answer\]

@austinL I think its D but Im not clearly sure
OpenStudy (anonymous):
So..
when I multiplied 7x6 that got me 42 but + 3 I have 45 on the numerator.
\[\frac{ 45 }{ 7 } \times \frac{ 1 }{ 12 }\]
so i multiply this and I get the answer right?
