Question

Viết thành hỗn số (theo mẫu) :

1 hm² 23 dam² = 1 hm² + \(\dfrac{23}{100}\) hm² = 1 \(\dfrac{23}{100}\) hm²

7 dam² 89 m² = 7 dam² + \(\dfrac{89}{100}\) dam² = 7 \(\dfrac{89}{100}\) dam²

a) 2 hm² 34 dam² = ............................................................................ = hm²

b) 5 dam² 67 m² = .............................................................................. = dam²

c) 12 dam² 3 m² = .............................................................................. = m²

Answer 1

a) 2 hm² 34 dam² = 2 hm² + \(\dfrac{34}{100}\) hm² = \(2\dfrac{34}{100}\) hm²
b) 5 dam² 67 m² = 5 dam² + \(\dfrac{67}{100}\) dam² = \(5\dfrac{67}{100}\) dam²
c) 12 dam² 3 m² = \(\dfrac{120000}{100}\) m² + 3 m² = \(\dfrac{120003}{100}\)m² = \(1203\dfrac{3}{100}\) m²
