You can’t record how clean someone’s hair is it depends on how they wash it and they probably wash it different every time. You could measure how dry their hair is after using that certain company’s shampoo.
If you would like to solve the following proportion 15 / 21 = 5 / x, you can do this as follows:
15 / 21 = 5 / x /*x
15 / 21 * x = 5 /*21
15 * x = 5 * 21 /15
x = 5 * 21 / 15
x = 7
The correct result would be C. 7.
