Answer:
Explanation:
To find what the ratio would be, we need to know what to multiply 5 & 3 by so that when we add them, we get 80. Let's assume the number we multiply by is x:
5x + 3x = 80
8x = 80
x = 80 / 8
x = 10
Now, we multiply 5 by 10 and 3 by 10
= 50:30
Your ratio would be 50:30
Double check: 50 + 30 = 80
