Answer:
5 and 10
Step-by-step explanation:
The numbers must be a multiple of 5.
They will be 5a, 5b.
5a+5b=15
∴a+b=3
When we say multiples, we only consider positive values.
→ a=1 and b=2
→ a=2 and b=1
The original numbers will be 5 and 10.
For your information,
Both of the numbers have a common factor 5. So they will be divisible by 5, they will be 5a, 5b.
