Question

x - 2/3 - 2/15 - 2/35 - 2/63 = 30 1/9(hỗn số nha)
Ai giúp mk, mk cho 3 tick

Answer 1

\(x-\frac{2}{3}-\frac{2}{15}-\frac{2}{35}-\frac{2}{63}=30\frac{1}{9}\)

\(x=31\)

Answer 2

\(30\frac{1}{9}\)= \(\frac{271}{9}\)

\(x-\frac{2}{3}-\frac{2}{15}-\frac{2}{35}-\frac{2}{63}=\frac{271}{9}\)

\(x=\frac{271}{9}-\left(\frac{2}{3}+\frac{2}{15}+\frac{2}{35}+\frac{2}{63}\right)\)

\(x=\frac{263}{9}\)

Answer 3

X - 2/3 - 2/15 - 2/35 - 2/63 = 30 1/9

X - 2/3 - 2/15 - 2/35 - 2/63 = 271/9

X= 271/9 + 2/63 + 2/35 + 2/15+ 2/3

X = 31

Answer 4

X - 2/3 - 2/15 - 2/35 - 2/63 = 30 1/9
X - 2/3 - 2/15 - 2/35 - 2/63 = 271/9
X= 271/9 + 2/63 + 2/35 + 2/15+ 2/3
X = 31
