Tolong dijawab beserta cara ^^

1. 2x + 3x = 70
5x = 70
x = 14 buah
3x - 2x = x = 14 buah (A)

2. 10.000.000 = 20 bulan
1 bulan = 500.000
8 bulan = 500.000 × 8 = 4.000.000 (A)

3. 1 menit = 80 lembar
340 lembar/x = 80 lembar/1 menit
x = 4 2/8 menit = 4 1/4 menit = 4 menit 15 detik (C)

4. 6 liter = 240 km
1 liter = 40 km
360 km/40 km × 1 liter = 9 liter (B)

5. 25 liter = 240 orang
5 liter = 48 orang
20 liter = 48 × 4 = 192 orang (B)

6. 48 ekor = 20 hari
12 ekor = 5 hari
60 ekor = 20 hari - 5 hari = 15 hari (D)

7. 18 hari = 16 orang
1 hari = 16/18 = 8/9 orang
12 hari = 8/9 × 12 = 32/3 = 10 2/3 = 10 orang (A)
