Answer 1

Explicación paso a paso:

Propiedad asociativa :

(a + b) + c = a + (b + c)

a. 3 + 5 + 8 = (3+5) + 8 = 16

b. 2/3 × 1/2 × 5/4 = (2/3 × 1/2) × 5/4 = 5/12

Propiedad distributiva :

a × (b + c) = a×b + a×c

a. 4 × (15 - 9) = 4×15 - 4×9 = 24

b. 1/4 × (2/5 + 1/2) = (1/4)×2/5 + (1/4)×1/2 = 9/40
