Đáp án:

Giải thích các bước giải:

1m2=...$\frac{1}{100}$ ........dam2

vì 1m2=...$\frac{1}{100}$ ........dam2

=>3m2=$\frac{3}{100}$dam2

vì 1m2=...$\frac{1}{100}$ ........dam2

=>45m2=$\frac{45}{100}$dam2

1mm2 =...$\frac{1}{100}$..cm2

=>4mm2=.....$\frac{4}{100}$...cm2

34mm2 =..$\frac{34}{100}$..cm2

1dam2 =....$\frac{1}{100}$ ...hm2

=>72dam2 =....$\frac{72}{100}$....hm2; 28dam2=....$\frac{28}{100}$...hm2

1dm2 =.....$\frac{1}{100}$.....m2

=>5dm2=.......$\frac{5}{100}$....m2 15dm2=......$\frac{15}{100}$....m2
