Kelas 10 Matematika
Bab Pengukuran

45 detik = (45/60) menit
45 detik = 0,75 menit

30 menit + 0,75 menit
= 30,75 menit
= (30,75/60) jam
= 0,5125 jam

45 jam + 0,5125 jam
= 45,5125 jam

45 jam 30 menit 45 detik

⇔45 detik :
[tex] = \frac{45}{60} [/tex]

[tex] = 0,75[/tex] menit

⇔30 menit + 45 detik :
[tex]= 30,45[/tex]menit

[tex] = \frac{30,45}{60} [/tex]

[tex] = 0,5125[/tex] jam

⇔45 jam + 30 menit + 45 detik :
= 45 jam + 0,5125 jam
= 45,5125 jam
