Answer 1

1.  1/2*1/3=1/6= 0,1666
2.   3/4*1/2*2/5= 6/ 40  = 3/20 = 0,15
3.  4/5*2,5*40%=  0,8
4.  1/4*1 1/3= 1/4 * 4/3 =4/12 = 1/3=0,3333
5.  2 2/3*1 3/5=  8/3 * 8/5 = 64/15 = 4  4/15= 4,2666
6. 2 2/5*3 1/4*1 1/2= 12/5*  13/4 * 3/2 =468/ 40 =11,7
7.  5*2/5= 10/5 = 2
8.  1/2:1/5= 1/2 x 5/1 = 5/2 = 2,5
9.  3/4:4=   3/4 x 1/4 = 3/16 = 0,1875
10.3 3/4:1 1/2:1/4=. 15/4  : 3/2 : 1/4
                         = 15/4 x 2/3 x 4/1
                        = 120 /12
                        = 10,00

Answer 2

1.1/2×1/3= 1/6
2. 3/4×1/2×2/5= 6/40= 3/20
3. 4/5×2,5×40%
= (4/5×20/20)×2,5×40/100
= 0,8×2,5×0,4
= 0,8
4. 1/4×4/3= 4/12=1/3
5. 8/3×8/5= 64/15 = 4 4/15
6. 12/5×13/4×3/2= 117/10= 11 7/10
7. 5×2/5= 10/5= 2
8. 1/2:1/5= 1/2×5/1 = 5/2= 2 1/2
9. 3/4×1/4= (3/4×25/25)×(1/4×25/25)
= 0,75×0,25= 0,1875
10. 15/4×2/3×4/1= 10

tolong dicek lagi ya takut salah ngitung
