Solution:
____________________
Distributive property:
A(B+C) = AB+AC
____________________
Here ,
A = -2/5 , B = 3/8 , C = -25
Now ,
(-2/5)[3/8+(-25)]
= (-2/5)(3/8) + (-2/5)(25)
= (-2×3)/(5×8) + (-2×25)/5
After cancellation, we get
= -3/20 - 10
= -3/20 - (10×20)/20
= -3/20 - 200/20
= (-3-200)/20
= -203/20
