Work: Calculate the value of equation ((18/5-2)*(18/5-6))/((-21/5+3)*(-21/5+1)) .
Question type: Mathematical calculation
Solution:
((18/5-2)*(18/5-6))/((-21/5+3)*(-21/5+1))
=(1.6*(18/5-6))/((-21/5+3)*(-21/5+1))
=(1.6*(-2.4))/((-21/5+3)*(-21/5+1))
=-3.84/((-21/5+3)*(-21/5+1))
=-3.84/((-1.2)*(-21/5+1))
=-3.84/(-1.2*(-3.2))
=-3.84/3.84
=-1
Answer:((18/5-2)*(18/5-6))/((-21/5+3)*(-21/5+1))=-1
