Question

Chuyển hỗn số thành phân số (theo mẫu) :

Mẫu : 2 \(\dfrac{3}{4}\) m² = \(\dfrac{2x4+3}{4}\) m² = \(\dfrac{11}{4}\) m²

3\(\dfrac{27}{100}\) km2 = \(\dfrac{......}{......}\) = \(\dfrac{......}{......}\)

5\(\dfrac{9}{100}\) mm2 = \(\dfrac{......}{......}\) = \(\dfrac{......}{......}\)

 

 

 

Answer 1

3x100+27/100=327/100 km²

5x100+9/100=509/100 mm²

Answer 2

\(3\dfrac{27}{100}km^2=\dfrac{327}{100}km^2\)

\(5\dfrac{9}{100}mm^2=\dfrac{5.100+9}{100}=\dfrac{509}{100}mm^2\)

Answer 3

3*100+27/100=327/100
