Answer:
Step-by-step explanation:
So, we se that there are 8 parts in total.
So, 50/8 is 6.25
So, 6.25*3 parts, which is how many there are for blue is 18.75
Since 5 miles is equaled to 4 inches multiply the 8 miles by 4/5 to get 6 2/5
To find this answer you simply subtract eight from sixty-two, which gives you....
54!
So there are 54 student in the science club!
