5607 dm² = 56 m² 7 dm²

\(\dfrac{4}{5}\) m = 8 dm

\(\dfrac{2}{5}\)m = 4 dm

ƯCLN(102, 45) = 3

\(\dfrac{102}{45}=\dfrac{102:3}{45:3}=\dfrac{34}{15}\)

95+2+98+5

=(95 + 5) + (2 + 98)

= 100 + 100

= 200

97 + 4 + 96 + 3

= (97 + 3) + (4 + 96)

= 100 + 100

=200

Số kg cam là: 516 * 30 = 15 480 (kg cam)
