1) Turn them into improper fraction

2) Multiply denominator by denominator, numerator by numerator.

3) Turn it back to mixed fraction

DONE!!

 

Examples:

\(1\dfrac{6}{13}\times 4\dfrac{17}{57}\\ =\dfrac{19}{13}\times \dfrac{245}{57}\\ =\dfrac{1}{13}\times \dfrac{245}{3}\\ =\dfrac{245}{39}\\ =6\dfrac{11}{39}\)

Of course you can simplify them, like what I did in step 2.
