Question

A= 19và1phần4+1phần2×và1phần3+ 5,75 - 1phần6+74

 

Answer 1

A = 19\(\dfrac{1}{4}\) + \(\dfrac{1}{2\dfrac{1}{3}}\) + 5,75 - \(\dfrac{1}{6}\) + 74

A = \(\dfrac{77}{4}\) + \(\dfrac{1}{\dfrac{7}{3}}\) + 5,75 - \(\dfrac{1}{6}\) + 74

A = \(\dfrac{77}{4}\) + \(\dfrac{3}{7}\) + \(\dfrac{23}{4}\) - \(\dfrac{1}{6}\) + 74

A = \(\dfrac{3234}{168}\) + \(\dfrac{72}{168}\) + \(\dfrac{966}{168}\) - \(\dfrac{28}{168}\) + \(\dfrac{12432}{168}\)

A =  \(\dfrac{16676}{168}\)

A = \(\dfrac{4169}{42}\)
