Question

Kak tolong jawab no 5 sampai 8

Answer 1

5. 1 1/2 + 25%
= 3/2 + 25/100
= 3/2 + 1/4 (kpk:4)
= 6+1/4 = 7/4 = 1 3/4 (C)

6. 85% - 2/5
= 85/100 - 2/5
= 17/20 - 2/5 (kpk:20)
= 17-8/20 = 9/20 (D)

7. 1/4 + 1/2 - 35%
= 1/4 + 1/2 - 35/100
= 1/4 + 1/2 - 7/20 (kpk:20)
= 5+10-7/20 = 8/20 = 0,4 (D)

8. 2 3/5 x 60%
= 13/5 x 60/100
= 13/5 x 3/5 = 39/25 = 1 14/25 (D)
