Question

\(\frac{30}{43}=\frac{1}{a+\frac{1}{b+\frac{1}{c+\frac{1}{d}}}}\)

Answer 1

30/43=1/43/30=1/1+13/30=1/1+1/30/13=1/1+1/30/13=1/1+1/2+4/13=1/1+1/2+1/13/4=1/1+1/2+1/3+1/4

vậy a=1, b=2, c=3, d=4

Answer 2

\(\frac{30}{43}=\frac{1}{\frac{43}{30}}=\frac{1}{1+\frac{13}{30}}=\frac{1}{1+\frac{1}{\frac{30}{13}}}=\frac{1}{1+\frac{1}{2+\frac{4}{13}}}=\frac{1}{1+\frac{1}{2+\frac{1}{\frac{13}{4}}}}=\)

$\frac{1}{1+\frac{1}{2+\frac{1}{3+\frac{1}{4}}}}$

Vậy a = 1 ; b = 2 ; c = 3 ; d =4

Answer 3

\(\frac{1}{1+\frac{1}{2+\frac{1}{3+\frac{1}{4}}}}\)
