To simplify the expression, we will first distribute the coefficients:
4/8(2.7m - 2) - 4.2(5/7m - 0.5n)
= 0.5(2.7m - 2) - 4.2(5/7m - 0.5n)
Next, we will simplify the expression by multiplying and combining like terms:
0.5(2.7m - 2) - 4.2(5/7m - 0.5n)
= 0.52.7m - 0.52 - 4.25/7m + 4.20.5n= 1.35m - 1 - 3m + 2.1n= -1.65m + 2.1n - 1
Therefore, the simplified expression is -1.65m + 2.1n - 1.
