bantu jawab dong,besok di kumpulin no.10,11,sama 12

10. 0,8 X 3/5= 0,8 X 0,6 = 0, 48
11.3/4 : 1/5 = 3/4 X 5/1 = 15/4 = 3 3/4

Maaf no. 12 nya gak ada

No 10 = 0,8 x 3/5
= 8/10 x 3/5
= 24/50 = 12/25 ( D )
No 11 =3/4 : 1/5
= 3/4 x 5 = 15/4 = 3 3/4 ( B)
No 12 = (3 3/4 - 1/4) : 3
= 3 2/4 : 3 = 14/4 : 3 = 14/4 x 1/3 = 14/12 = 1 1/2 m ( A )
Semoga membantu.
