Answer 2

1. 1 jam = 3600 detik
1 2/5 jam = 7/5 x 3600 detik
= 1540 detik

2. 1 menit = 60 detik
10.800 detik + 240 menit =
(10.800 : 60) menit + 240 menit =
180 menit + 240 menit = 420 menit

3. 1 are = 1 dam2
1 are = 100 m2
1 1/4 dam2 + 2 3/4 m2 =
1 1/4 are + (2 3/4 : 100) are =
1 1/4 are + 2 3/400 are =
1, 25 are + 0,0275 are = 1, 2275 are

4. 1 liter = 1000 cc
Harga 1/4 liter = Rp 1500/cc × (1/4
x 1000cc) = Rp 1500 x 250 =
Rp 375.000
