Question

Tìm số thập phân thích hợp.

Answer 1

a) 8 m² 75 dm² = $8\frac{{75}}{{100}}$m² = 8,75 m²                                                  

   3 m² 6 dm² = $3\frac{6}{{100}}$ m² = 3,06 m²

   120 dm² = $\frac{{120}}{{100}}$ m² = $1\frac{{20}}{{100}}$m² = 1,2 m²                     

b) 4 dm² 25 cm² = $4\frac{{25}}{{100}}$ dm² = 4,25 dm²

    2 dm² 5 cm² = $2\frac{5}{{100}}$ dm² = 2,05 dm²    

     85 cm² = $\frac{{85}}{{100}}$ dm² = 0,85 dm²
