The ratio is 1:7. This means there are 8 total parts. Start by dividing 40 by 8. This equals 5. Each part equals five, so the white marbles are 5. However, question asks for the number of RED. 7 of the 8 parts are red. 7*5 is 35 so there are 35 red marbles.

Answer:
Step-by-step explanation:
If we have an equation 
and we want to find what b is in relation to a, we can change the equation so that we have b on one side and whatever is on the other side is what b is.
To isolate b, we can take the square root of both sides as taking the square root of something squared results in the base.
So b is the square root of a.
