no.7 caranya seperti apa? (smp kelas 7) jawabnya a-e

a. 1/3 × 3/4 × 2/5 = 1/4 × 2/5 = 1/10
b. (1/3 × 3/4) - (1/3 × 2/5) = 1/4 - 2/15 = 15 - 8/60 = 7/60
c. (3/4 - 2/5) × 1/3 = (15 - 8/20) × 1/3 = 7/20 × 1/3 = 7/60
d. 2(1/3 × 3/4) : 2/5 = (2 × 1/4) : 2/5 = 1/2 × 5/2 = 5/4 = 1 ¼
e. (2/3 × 3/4) - (1/2 × 2/5) = 1/2 - 1/5 = 5 - 2/10 = 3/10.

Semoga membantu.
