and denominator of the other fraction below.
Use
small numbers so that it can be understood better.

 Count
the resulting parts, this will be the numerator of the product.

Count the parts forming a unit square, this will be the denominator of
the product.
 What is
the relation between the numerator of the product and the numerators of
the factor fractions?
 What is the relation between the denominator of the product and the
denominators of the factor fractions?
This
way, you can deduce the method to obtain the product of two fractions
numerically.
