A cleaning solution mixture calls for a ratio of 1 part bleach for every 4 parts water. When mixing the solution, Aki made a mistake and mixed in half as much bleach as was required by the ratio. The total solution consisted of 27 milliliters. How much bleach did Aki put into the solution, in milliliters?
(A) 3
(B) 4
(C) 6
(D) 7
(E) 8
We can read this Qs as - how much is \(a\) in \(a : b\)?
\(a = \frac{a}{(a + b)}(total)\)
Bleach = \(\frac{0.5}{(4.5)}(27) = \frac{27}{9} = 3\)
Hence, option A
