Answer:
It is the 3rd choice
Explanation:
The ratio of red candies to blue is 5:3 as you probably learned, the ratio ':' sign also means the fraction division sign. So we can also write this as 5/3. Lastly how we READ a ratio is; something TO something. In this case if we were to read 5:3 we would say " Five to Three" since there is no choice spelling out the numerals we can just say " 5 to 3". All of these ways are given in the 3rd answer choice.
I hope this helps!
