ANSWER D.
d
To find the pair of numbers that has the same product and sum, we need to calculate the product and sum of each pair of numbers given.
Let's start with option A: 1,1. The product of these numbers is 1*1=1, and the sum is 1+1=2. Therefore, the product and sum are not the same for this pair.
Now let's move on to option B: 0,2. The product is 0*2=0, and the sum is 0+2=2. In this case, the product and sum are the same.
Next, we have option C: 1,0. The product is 1*0=0, and the sum is 1+0=1. Again, the product and sum are not the same for this pair.
Lastly, we have option D: 2,2. The product is 2*2=4, and the sum is 2+2=4. Here, the product and sum are the same.
Therefore, the pair of numbers that has the same product and sum is option D: 2,2.
