Answer:
124÷2=62
Step-by-step explanation:
Each person has 62 marbles.
The beginning of the problem is not needed to answer the question. The only thing you need to know to answer the question is that they have 124 marbles together.
Using the information from the question, one can construct two equations:

... (1)

... (2)
by substituting (1) into (2) to find x


\frac{5}{4z} = \frac{1}{4}



⇒ z = 5
By substituting value of z into (1)
⇒ 4 (5) = x
⇒ x = 20
Thus the two numbers are 5 & 20
