Question

2 per 5 dikali 0,4 dibagi buka kurung 3/8 kura 0,075 sama dengan ?cara kerjanya!<br />

Answer 1

(2/5×0,4)/(3/8-0,075)=(2/5×2/5)/(3/8-3/40)=(4/25)/(12/40)=(4/25)(40/12)=120/300=4/10

Answer 2

2/5 x (0,4=4/10) : {(3/8 - (0,075=75/1000) }
2/5 x 4/10 : (3/8 - 75/1000)
2/5 x 4/10 : (1500/4000 - 300/4000)
2/5 x 4/10 : 1200/4000{disederhanakan 3/10}
4/25 : 3/10 = 4/25 x 10/3 = 8/15
