= (four-fifths * three-thirds) divided by (one-third * three-thirds) according to (numerator and denominator are multiplied by a non-zero number, and the size of the fraction remains the same)

= (4*3)* ( 1/5)

= 12/5

Two sevenths divided by three fifths.

=(7*5) divided by (2 * 3)

=35*( 1/6)

=35/6

I see, a number divided by a number that is not equal to 0 is (multiplied by) the (reciprocal) of this number.
