There are an infinite number of them.
Here are a few of them:
1.50000000000001

etc.
They are 23 and 29
41, 43, 47
Two of them and they are 23 and 29
The two numbers needed are 25 and 15
It is: 13+17 = 30
They are 23 and 29
41, 43, 47
Two of them and they are 23 and 29
That's the GCF.
The two numbers needed are 25 and 15
More composite nubers.
It is; 2*3 = 6
How about 80+6 = 86 as one example
The nubers are: 16 and -27
It is: 13+17 = 30
2 7/15 + 1 4/5 first find the common denominator, in this case its /15 and since to make the 4/5 into the 15 you have to multiply both top and bottom nubers by 3. making it 1 12/15 2 7/15 + 1 12/15 = 3 19/15 then reduce the fraction 4 4/15
1000/2 is one possible pair.
