1.) 4/5 tahun+ 5/6 bulan - 3 minggu...hari 2.) 4/5 jam + 3/6 jam - 5/10 jam ... menit 3.) 3/6 jam - 2/10 jam - 4/15 jam ... menit 4.) 3/20 jam + 3/12 jam + 1/2

1 Tahun = 360 Hari
1 Bulan = 30 Hari
1 Minggu = 7 Hari

Jawab
1.) 4/5 × 360 = 288 Hari
5/6 × 30 = 25 Hari
3 minggu = 7 × 3 = 21 Hari
= 288 + 25 - 21
= 292 Hari

1 Jam = 60 Menit

Jawab
2.) 4/5 × 60 = 48 Menit
3/6 × 60 = 30 Menit
5/10 × 60 = 30 Menit
= 48 + 30 - 30
= 48 Menit

Jawab
3.) 3/6 × 60 = 30 Menit
2/10 × 60 = 12 Menit
4/15 × 60 = 16 Menit
= 30 - 12 - 16
= 2 Menit

Jawab
4.) 3/20 × 60 = 9 Menit
3/12 × 60 = 15 Menit
1/2 × 60 = 30 Menit
= 9 + 15 + 30
= 54 Menit

Jawab
5.) 3/4 × 60 = 45 Menit
5/12 × 60 = 25 Menit
1/3 × 60 = 20 Menit
= 45 - 25 + 20
= 40 Menit

Semoga Membantu :)
