The first step is converting the mixed number into an improper fraction. Your answer is 3/4
1/2 + 1/4 + 2/5
=(2+1)/4 + 2/5
=3/4 +2/5
=(3*5+2*4)/4*5
=(15+8)/20
=23/20
Answer:
The correct answer is P= -6.4
Step-by-step explanation:
By clearing P from the equation P+0.4=-6, we have:
P +0.4=-6 , subtracting 0.4
P +0.4-0.4 = -6-0.4
→ P = -6.4
