Tolong jawab besok mau dikumpulkanpliss jawab kk
Jawaban:
6. 6 x 2 3/4 x 0,25 = 4 1/8
= 6 x (11/4) x (25/100)
= 6 x (11/4) x (1/4)
= 66/16 (sama-sama dibagi 2)
= 33/8 = 4 1/8
7. 4 5/4 x 2,4 x 3 = 4 1/5
8. 2,8 x 1 1/6 x 2 = 6 8/15
10. 4,25 : 4/9 : 0,75 = 12 5/4
= (425/100) : (4/9) : (75/100)
= (425/100) x (9/4) x (100/75)
= 425 x (9/4) x (1/75)
= 3.825/300 (sama sama di bagi 75)
= 51/4 = 12 5/4
12 5/4
