Tolong jawab yh!! pakai caranya pliss soalnyah besok dikumpulin #Jawab yh

1. 4 4/5 ÷ 12/10 × 9/11
= 24/5 ÷ 12/10 × 9/11
= 24/5 × 10/12 × 9/11
= 36/11
= 3 3/11
2. 7 + 4 = 11
Uang A = 7/11 × 55.000 = 35.000
Uang B = 4/11 × 55.000 = 20.000
Maka, selisih = 35.000 - 20.000 = Rp.15.000,-
3. 0,75 ; 1 2/5 ; 60% ; 7/8
75/100 ; 7/5 ; 60/100 ; 7/8
75/100 ; 140/100 ; 60/100 ; 87,5 /100
→ 60% ; 0,75 ; 7/8 ; 1 2/5
4. 4 ons = 4/10 kg = 2/5 kg
Maka, 3 1/4 + 1/2 + 2/5
= 3 5/20 + 10/20 + 8/20
= 3 23/20
= 4 3/20 kg
