(-2/3 + 5/12) + (-0.45)
To add fractions, we need a common denominator. The least common denominator between 3 and 12 is 12.
Converting -2/3 to have a denominator of 12:-2/3 = -8/12
Therefore, we have (-8/12 + 5/12) + (-0.45)= (-3/12) + (-0.45)= -3/12 - 45/100= -3/12 - 54/120= -30/120 - 54/120= -84/120= -7/10
Therefore, (-2/3 + 5/12) + (-0.45) = -7/10.
