1 * x = x.

So,

\frac{1}{6} * \frac{11}{21} = \frac{11}{126}

shouldn't it be D?

\((\frac{7}{6})*(\frac{32}{21})=(\frac{1}{6})*(\frac{32}{3})=\frac{1}{3}*\frac{16}{3}=\frac{16}{9}=1*\frac{7}{9}\)

A is the answer

A is the answer


So, the question must be \((1+(\frac{1}{6})) * (1+(\frac{11}{21}))\) ?

Oh, I see. I thought the numbers in the parentheses were being multiplied by 1, but they are in mixed fraction form. This makes much more sense now. Thanks a lot! :D

BUT mixed fraction like this \((1*\frac{1}{6})\)

and this

\((1 \frac{1}{6})\)

Are the same

\(1\) is \(\times\) \(1/6\)
