Answer 1

3/4 jam      = 45 menit
720 detik  = 12 menit
3/4 jam + 720 detik = 57 menit

 

Answer 2

3/4 jam = 45 menit

720 det = 12 menit.

Jadi,

45 + 12 = 57 menit.

Cara dijadiin menit :

1 jam = 60 menit

3/4 jam = 60 : 4 = 15
= 15 x 3
= 45 menit

1 menit = 60 detik

720 det. = 720 : 60 = 12 menit
