kak tolong dikit lagi berangkat

Answer 1

Jawaban:

9 - 5/12

= 108/12 - 5/12

= 103/12 = 8 7/12

....

4/5 + 8 - 60%

= 4/5 + 40/5 - 60/100

= 44/5 - 3/5

= 41/5 = 8 1/5

....

(3 3/4 + 0,4) - 1/4 + 5%

(15/4 + 4/10) - 1/4 + 5/100

(75/20 + 8/20) - 1/4 + 1/20

67/20 - 5/20 + 1/20

63/20 = 3 3/20

.....

12 - 5 4/25 + (16% - 0,2)

12 - 129/25 + (0,16 - 0,2)

12 - 129/25 - 0,04

300/25 - 129/25 - 4/100

1200/100 - 516/100 - 4/100

680/100 = 68/10 = 6 8/10 = 6 4/5
