32

Step-by-step explanation:

In your head: 1/5 of 40 is 8 (since you know 5×8 = 40). Then 4 times that is 32 (since you know 4×8 = 32).

Your calculator can do this, too.

(4/5)·40 = 32

_____

In decimal, it is 0.8 · 40 = 8·4 = 32. Some folks are taught to do this sort of multiplication by taking a factor of 10 from one number and applying it to the other number. That is ...

... 0.8 × (10 × 4) = (0.8 ×10) × 4

... = 8 × 4 = 32

You can do substantially the same thing with the fraction.

... (4/5) × (5 × 8) = (4/5 × 5) × 8

... = 4 × 8 = 32
