There are infinitely many possible answers:
Two such are 1*45 and 10*4.5
It is: 3*3*5 = 45 or as 32*5 = 45
4 and 45
15 and 3
The product of two prime numbers can never be another prime number, the numbers that you multiplied are factors of the product. (example, 9 times 5 is 45, 9 and 5 go into 45)
The numbers are 15 and 3. 15 * 3 = 45 15 + 3 = 18
3 & 15
45 and 50
45 = 3 x 3 x 5
9 and 5
45 = 3 x 3 x 5 or 32 x 5
-33
They are 9 and 5
