tolong di bantu pakai cara ya

No 2 : kue = 3 loyang
kue Dibagi= 32 bagian
Dibagi ke = 16 anak
Jadi, 3×32÷16= 96÷16 = 6 bagian

No 3: 72 ÷ 6 - (-5) × 8 = 12-(- 40)
= 52

No 4:
Km = 3 1/4 - 25/10
= 12/4 - 25/10
= 60/20 - 50/20
= 10/20
= 1/2 + 3/4
= 2/4 + 3/4
= 5/4
= 1 1/4

No 5:
0,8 = 8/10
25%= 25/100
8/10 : 2/3 = 8/10 × 3/2=24/20 × 25/100= 6/5 × 1/4 = 6/20


Maaf kalo salah
