I think a table can be very helpful for somebody to understand.
00:04
So we're doing number of sugar versus number of flour.
00:10
And they say three cups of flour for every two cups of sugar.
00:16
So that means if you have four cups of sugar, then you have six cups of flour or nine and six.
00:24
And you could see exactly what's happening is for any situation, i mean, i could even talk about cups over here.
00:34
What's happening is to get the answer for n of sugar.
00:42
Whoops, n of sugar, it's equal to two times whatever the variable is.
00:52
And the number of flour is equal to three times whatever that number is.
00:56
I don't know, maybe i should call this batches instead of cups.
01:03
So either way that you're talking about doing this, you could set up some sort of formula where you could just divide it.
01:15
And i don't know if that makes any sense.
01:17
But n of sugar divided by n of flour needs to be equal to 2 over 3.
01:29
And the reason why the x's sort of drop out is because anything divided by itself would equal 1.
01:36
So what you can do is you could cross multiply as n of s is equal to two thirds n of f.
01:45
So if you have three cups of flour, the threes would cancel out.
01:51
So this would be a good formula, or you could flip them...
