1. 2 6/8 - 9/10 = 2. 0,8 x 2/5 = 3. 12% x 4 1/6 = 4. 3 3/7 x 4/6 = 5. 6% x 50/60 = Tolong dijawab pakai soal..

1. 22/6-9/10=220/60-54/60=220-54/60=166/60=dua 46/60
2. 3,6/5

1. 2 6/8 - 9/10
= 22/8 -9/10
= 110/40 -36/40
= 74/40= 1 34/40

2. 0.8= 4/5
=4/5 * 2/5
= 8/25

3. 12%= 12/100
= 12/100 * 4 1/6
= 12/100 * 25/6
= 100/300= 1/3

4. 3 3/7 = 24/7
24/7* 4/6
= 16/7 = 2 2/7

5. 6/100 * 50/60
= 1/20
