\(x=\frac{2}{5}:\frac{1}{18}\)

\(x=\frac{26}{5}\)

Answer 6

\(\frac{2}{5}:x=\frac{1}{8}\)

       \(x=\frac{1}{8}x\frac{2}{5}\)

       \(x=\frac{5}{16}\)

Answer 7

\(\frac{2}{5}:x=\frac{1}{18}\)

       \(x=\frac{1}{18}x\frac{2}{5}\)

        \(x=\frac{2}{90}\)

Answer 8

x = 1/18 : 2/5

x= 5/36

Answer 9

\(\frac{2}{5}:x=\frac{1}{18}\)

       \(x=\frac{36}{5}\)

Answer 10

2 /5 : x = 1 /18

Answer 11

X x 49/10 + X x 1/10 = 21/2

X x(49/10 + 1/10) = 21/2

X x 5 = 21/2

X=21/2 : 5 

X=21/10
