To figure out the HCF of 28 and 60, split them up into their prime factors: 28 = 2x2x7 60 = 2x2x3x5 The next step is to identify any common prime factors. In this case, both numbers have two 2s as prime factors. Multiply these together and you get: 2x2 = 4 Therefore 4 is the HCF of 28 and 60.
The two numbers you are looking for are -15 and 4. When you multiply -15 and 4, you get -60, and when you add them together, you get -13.

Multiply 4 by 15 to make 60. Multiply 4 by 25 to make 100

If you've written that correctly, there aren't two whole numbers that satisfy your conditions. -30 and 2 multiply to -60, but they add to -28.
I hope you would multiply 15 by 4 if you want to get 60 to give to me.
make the two numbers into a fraction and multiply by 100 Example: 3 as a fraction of 5 is 3/5 x 100 = 300/5 = 60/1 = 60%
