Mapel : Matematika
Tentang : Pecahan
Pembahasan :

[tex] \frac{3}{4} = \frac{3 \times 25}{4 \times 25} = \frac{75}{100} = 0.75[/tex]

[tex] 1\frac{1}{2} = \frac{3}{2} = \frac{3 \times 5}{2 \times 5} = \frac{15}{10} = 1.5[/tex]

Total : 0,75 + 1,5 + 1,5
Total : 3,75 jam

Jika dijadikan pecahan menjadi :

3,75 = 375/100 = (375 : 25)/(100 : 25) = 15/4

Jawaban : 3,75 jam atau 15/4 jam

Heil Manstein!

3/4 + 1 1/2 + 1,5
3/4 + 3/2 + 3/2
3/4 + 6/2
15/4 jam atau 3,75 jam

Maaf kalau salah
Semoga membantu
