We can use ratios and the cross-multiply-divide to find this.
The ratio 21:5 is avaliable via the question. We then need to compare that to the ratio x:100, the 100 being the percent and the x being the number of airplane parts.
21/5 = x/100
We can then solve for x to find the number of airplane parts. First we multiply by 100 on both sides to get 2100/5 = x. Therefore x = 420 and there are 420 airplane parts.
The 2 in 324 represents the number 20 out of 300 and 4. With decimal in front, the 2 now represents hundredths of 1.
I created this using a graphing calculator website called Desmos! You can use this to further explore slopes and lines and graphing in general :)
