5 tahun = 5 x 12 = 60 bulan
3 bulan = 3 bulan
8 minggu = 2 bulan
__ _________+
= 65 bulan
30 hari = 1 bulan
_________ -
= 64 bulan
semoga jawaban betul

1) 5 th + 3 bln + 8 Minggu - 30 hari
= (5 × 12) + 3 + (8 ÷ 4) - (30 ÷ 30)
= 60 + 3 + 2 - 1
= 64 bulan

2) ½ gross + 1¼kodi + 3 lusin
= (½ × 144) + (1¼ × 20) + (3 × 12)
= 72 + 25 + 36
= 133 biji

3) 50 hal + 7500 dl + 870 cm³ - 2,5 dm³
= (50 × 100) + (7500 ÷ 10) + (870 ÷ 1000) - (2,5 × 1)
= 5000 + 750 + 0,87 - 2,5
= 5748,37 ltr

4) 500kg + 7500gr + 50 ons - 7 pon
= 500 + (7500 ÷ 1000) + (50 ÷ 10) - (7 ÷ 2)
= 500 + 7,5 + 5 - 3,5
= 509 kg

5) 25 hm² + 800 dam² - 65.000 m² - 3.075.000 dm²
= 25 + (800 ÷ 100) - (65.000 ÷ 10.000) - (3.075.000 ÷ 1.000.000)
= 25 + 8 - 6,5 - 3,075
= 23,425 hm²
