Tolong saya ntar kasih poin banyak pls jawab

Jawab:
1. 0,9 – 15/20
= 9/10 – 15/20
= 180 – 150/200
= 30/200
= 3/20

2. 0,76 – 2/5
= 76/100 – 2/5
= 380 – 200 /500
= 180/500
= 18/50
= 9/25

3. 1,67 – 9/50
= 1,67 – 0,18
= 1,49

4. 2,01 – 1 3/10
= 2,01 – 13/10
= 2,01 – 1,3
= 0,71

5. 2,9 – 1 9/25
= 2,9 – 34/25
= 2,9 – 1,36
= 1,54

6.34/50 – 0,43
= 0,68 – 0,43
= 0,25

7.

1 . 0,9 – 15/20 = 9/10 – 15/20
= 18 – 15 = 3/20 = desimal = 0,15

2 . 0,76 – 2/5 = 76/10 – 2/5
= 76 – 4 = 72/10 = desimal = 0,36

3 . 1,67 – 9/50 = 1,67 – 0,18
= 1,49

4 . 2,01 – 1 3/10 = 2,01 – 0,30 = 1,71

5 . 2,0 – 1 9/25 = 2,0 – 1,36 = 0,64

6 . 34/50 – 0,43 = 0,68 – 0,43 = 0,25

7 . 1 2/4 – 0,70 = 1,5 – 0,70 = 0,8

8 . 2 4/10 – 1,24 = 2,4 – 1,24 = 1,16

9 . 3 5/20 – 2,01 = 3,25 – 2,01 = 1,24

10 . 3 3/50 – 1,48 = 3,06 – 1,48 = 1,58

# ini jawabannya aku bentuk me desimal semua biar simple
