Question

Số?

Answer 1

a) 173 cm = $\frac{{173}}{{100}}$ m = $1\frac{{73}}{{100}}$ m = 1,73 m                               

82 dm =$\frac{{82}}{{10}}$ m = $8\frac{2}{{10}}$ m = 8,2 m                                          

800 kg = $\frac{{800}}{{1000}}$ tấn = 0,8 tấn

b) 3 dm² =$\frac{3}{{100}}$ m² = 0,03 m²                                       

1 m² 5 dm² = $1\frac{5}{{100}}$ m² = 1,05 m²                        

3 dm² 75 cm² = $3\frac{{75}}{{100}}$ dm² = 3,75 dm²
