426 g + 3 cg=mg
15 dg + 17 mg =mg
21 dg - 30 cg =mg
​

Answer 1

c)

47 g + 6 dg =dg

47 g = 470 dg

470 dg + 6 dg = 476 dg

426 g + 3 cg=mg

426 g = 426 000 mg

3 cg = 30 mg

426 000 mg + 30 mg = 426 030 mg

15 dg + 17 mg =mg

15 dg = 1 500 mg

1 500 mg + 17 mg = 1 517 mg

21 dg - 30 cg =mg

21 dg = 2 100 mg

30 cg = 300 mg

2 100 mg - 300 mg = 1 800 mg
