jika diketahui a=1/3,b=3/4,dan c=2/5,maka tentukan nilai operasi berikut! e.2/3b-1/2c

2/3b-1/2c
= 2/3•3/4 - 1/2•2/5
= 6/12 - 2/10
= 30/60 -12/60
= 18/60
= 3/10

semoga bermanfaat
maaf ya kalau salah^^

2/3b - 1/2c = (2/3 kali 3/4) (1/2 kali 2/5) = 6/12 - 2/10 = 60/60 - 12/60 = 48/60 = 24/30 = 12/15 = 4/5
