kaka kaka yg cantik dan ganteng plizzz kasih tau ntr yg jawaban nya benar aku tandai yg terbaik

1) 4½ th + 7 th + 24 bln
= 4,5 th + 7 th + (24 ÷ 12)
= 11,5 th + 2 th
= 13,5 th

2) 1 jam 45 menit - 1 jam 15 menit
= 30 menit

3) 06.30 + 480 menit
= 06.30 + ( 480 ÷ 60)
= 06.30 + 8 jam
= 14.30

4) 87 - 55 th = 32 th ÷ 8 = 4 windu

5) 7 semester + 3 bulan
= (7 × 6) + 3
= 42 + 3
= 45 bulan

1) 7+4,5+2 = 13,5th
2) 45-15 = 30 menit
3) 480 menit = 8jam . maka 6:30+8 = 14:30 ( jam 14:30)
4) 87-55 = 32 tahun
1 windu = 8 thn
Maka 32/8 = 4 windu
5) 7 smester = 7x6 = 42
42 + 3 = 45 bulan
