Answer:
-13/20 or -0.65
Explanation:
The equation is:
b - c + d
Insert all the value of b, c and d into the above equation:
b - c + d = -3/4 - 0.4 + 1/2
Solve the above inserted value:
= -3/4 - 0.4 + 1/2
= -3/4 - 4/10 + 1/2
= -3/4 - 2/5 + 1/2
= -3/4 + 1/2 - 2/5
= -3/4 + 2/4 - 2/5
= -1/4 - 2/5
= -5/20 - 8/20
= -13/20 or -0.65
Hope it helps. Thanks!
