(30/140) 1/6
You made a caresless error anon. So it is not quite right :(
$$\\\frac{30}{140}\times\frav{1}{6}\\\\ =\frac{3}{14}\times\frac{1}{6}\\\\ =\frac{1}{14}\times\frac{1}{2}\\\\ =\frac{1}{28}$$
(30/140) x (1/6)
30/140 becomes 3/14
(3/10) x (1/6)
to multiply fractions, you multiply the numerators together and the denominators together.
(3x1)/(10x6)
3/60 <=> 1/20
the answer is 1/20
