Answer 1

1)  9 : 4 = 360 : 160  ( × 40) = 36:16
2)  9:4 = 720 : 320  ( × 80 ) jari perempuan = 320
3) 3 1/5 - 1 1/6 = 16/5 -7/6 = 1/2
4) 3 1/5 : 1 1/6 = 16/5 × 6/7 = 96/35 =2 36/35
5) 3 1/5 + 11/6 = 16/5 + 11/6 = 19/8 = 2 3/8
 
Semoga membantu

Answer 2

1. Jari laki-laki = 9/9-4 × 200 = 9/5 ×200 = 360
Jari perempuan = 4/9-4 × 200 = 4/5 × 200 = 160

2. Jari laki-laki = 9/9+4 × 780 = 9/13 × 780 = 540
Jari perempuan = 4/9+4 × 780 = 4/13 ×780 = 240

3. 3 1/5 - 1 1/6 = (3-2) 1/5 - 1/6 = (3-2) 6/30 - 5/30 = 1 1/30

4. 3 1/5 ÷ 1 1/6 = 16/5 ÷ 7/6 = 16/5 × 6/7 = 96/35 = 2 26/35

5. 3 1/5 + 1 1/6 = (3-2) 1/5 + 1/6 = (3-2) 6/30 +5/30 = 1 1/30
