The first thing i would do is think about how we have 35 % and pure means 100%.
00:08
But what i would do is change these to decimal, so 0 .35 and 1.
00:14
And what i know is that we need to, well, they want you to replace the 35%.
00:22
So i'm going to call this one x.
00:24
And that 10 liter is important because then you do 10 minus x.
00:29
And notice how i'm kind of setting up a chart really.
00:31
Real quick because what i do is i multiply, well, i guess the top is actually just labeling, but you multiply as you go down.
00:42
So 0 .35 times 10, i'll just leave it like this, and then multiplying straight down is 1x...
