Tolong bantuin kak besok di kumpulin
yg gambarnya gk jelas tanya ke saya aja

Answer 1

1. 3 7/8 - 2 1/2 = 31/8 - 5/2
= 62/16 - 40/16
= 22/16 = 11/8 = 1 3/8

2. 3 3/5 - 1 7/15 = 18/5 - 22/15
= 270/75 - 110/75
= 160/75 = 32/15 = 2 2/15

3. 4 1/4 - 2 7/15 = 17/4 - 37/15
= 255/60 - 148/60
= 107/60 = 1 47/60

4. 5 5/6 - 2 3/9 = 35/6 - 21/9
= 315/54 - 126/54
= 189/54 = 21/6 = 3 3/6

5. 3 3/8 - 1 2/3 = 27/8 - 5/3
= 81/24 - 40/24
= 41/24 = 1 17/24

6. 9 3/6 - 5 2/4 = 57/6 - 22/4
= 228/24 - 132/24
= 96/24 = 16/4 = 4/1 atau 4 = 3 1/1 (pecahan camapuran)

7. 7 3/5 - 2 5/6 = 38/5 - 17/6
= 228/30 - 85/30
= 123/30 = 41/10 = 4 1/10

8. 5 4/5 - 3 3/8 = 29/5 - 27/8
= 232/40 - 135/40
= 97/40 = 2 17/40

Maaf kalau salah
