1. 120 jam+ 3minggu-10 hari=...hari 2. 6 kodi 2lembar 2 kodi 15 lembar= ....lembar

1.)
⇔120 jam + 3 minggu - 10 hari

⇔(120÷24) + (3×7) - (10×1)

⇔( 5 + 21 - 10 ) hari

⇔16 hari

2.)
⇔6 kodi + 2 lembar + 2 kodi + 15 lembar

⇔(6×20) + (2×1) + (2×20) + (15×1)

⇔( 120 + 2 + 40 + 15 ) lembar

⇔ 177 lembar

1. 120 jam = 5 hari ( 1 hari =24 jam )
3 minggu = 21 hari ( 1 minggu = 7 hari )

PENYELESAIAN:

5 HARI + 21 HARI - 10 HARI =16 HARI/ 384 jam/ 2 minggu lebih 2 hari



2. 1 kodi = 20 lembar

6 kodi + 2kodi = 8 kodi = 160 lembar

2 lembar + 15 lembar = 17 lembar

jadi,

160 + 17 = 177 lembar
