48% x 6 2/3 - 2 1/5 : 0,75 =

48/100x20/3 = 960/300 = 32/10 = 3 1/5
11/5x100/75 = 1100/375 = 44/15 =2 14/15
2. 14/15-3. 1/5
44/15-32/10
88/30-96/30
96/30-88/30 = 4/15

48% x 6 2/3 - 2 1/5 : 0,75 =
= 48/100 x 20/3 - 11/5 : 75/100
= 16/5 - 11/5 : 75/100
= 16/5 - 11/5 x 100/75
= 16/5 - 220/75
= 240 - 220 / 75
= 20/75
maka bisa disederhanakan menjadi
= 4/15
jawabanya B.
