1. 7kg=...gram 2. 7m+8dm=...cm 3. 6kg+9 ons=...gram 4. liat gambar cari sudut tumpulnya adalah...?? mohon bantuannya makasi

1kg = 1.000g.
7kg = 7 × 1.000 = 7.000g.

---------------------------------------

1m = 100cm.
7m = 7 × 100 = 700cm.

1dm = 10cm.
8dm = 8 × 10 = 80cm.

= 700 + 80.
= 780cm.

---------------------------------------

1kg = 1.000g.
6kg = 6 × 1.000 = 6.000g.

1ons = 100g.
9ons = 9 × 100 = 900g.

= 6.000 + 900.
= 6.900g.
