Viết các hỗn số sau thành số thập phân

a) \(7\dfrac{3}{10}\) b) \(9\dfrac{25}{100}\) c) \(3\dfrac{2}{5}\) d) \(7\dfrac{1}{4}\) e) \(1\dfrac{1}{25}\)

Answer 1

\(7\dfrac{3}{10}=\dfrac{73}{10};9\dfrac{25}{100}=\dfrac{37}{4};3\dfrac{2}{5}=\dfrac{17}{5};7\dfrac{1}{4}=\dfrac{29}{4};1\dfrac{1}{25}=\dfrac{26}{5}\)

Answer 2

a) \(7\dfrac{3}{10}=\dfrac{73}{10}=7.3\)

b)9\(\dfrac{25}{100}=9\dfrac{1}{4}=\dfrac{37}{4}=9.25\)

c)3\(\dfrac{2}{5}=\dfrac{12}{5}=2.4\)

d)\(7\dfrac{1}{4}=\dfrac{29}{4}=7.25\)

e)1\(\dfrac{1}{25}=\dfrac{26}{25}=1.04\)
