Well you can either think of actually dividing the fraction or reduce to lowest forms which is 1/2. then from 1/2 you can either divide that or just say it is .5.
I believe it’s true not 100% sure

Hello!
As we can see, they sell 2/5 as many white milks and chocolate milks. We can write this as the ratio 2:5. As you can see, we are given the total, which is 35. The total of the ratio in simplest form is 7 (2+5). As you can see, we have to multiply by 5 to get that 7 to 35. Therefore we multiply each part of the ratio by 5 to get our final answer. We can have w represent the white milks while c represents the chocolate milks.

Therefore there were 25 chocolate milks sold (just to verify 10 is 2/5 of 25).
I hope this helps!
Two hundred would be appropriate for a random sample. It doesn't get everyone involved yet has a sustainable amount of people.
