Answer:

Your statement is untrue. Correct derivations are below.
#4 2/3*-1 1/2 = -7#
#4 2/3 - 1 1/2 = 3 1/6#

Explanation:

First, put all of the fractions into forms with the same denominator (Greatest Common Factor) for addition/subtraction problems. Then do the algebraic function(s) and finally simplify the fraction, if any.

In this case we have a multiplication, so we can just convert the mixed number to a fraction first, then multiply and then simplify.

#4 2/3*-1 1/2 = 1 1/4# If this is a multiplication, the result should be negative.
#(3*4 + 2)/3* (2*-1 + 1)/2 = ?#

#14/3* -3/2 = ?# ; #-42/6 = -7# Doesn't look like your problem.

Let's try it as an addition:
#4 2/3 - 1 1/2 = 1 1/4#
#(3*4 + 2)/3 + (2*-1 + 1)/2 = ?#
#14/3 -3/2 = ?# ; #2*(14/3) - 3*(3/2) = ?#
#28/6 - 9/6 = 19/6#; #19/6 = 3 1/6#
