Holland added three decimals that made a sum of 2. one of the decimals was 0.34. what are two other decimals holland could have used to make a sum of 2

Using x to represent our missing values and the fact that there are two missing values gives us x + x = 2x. Because it's the sum of these numbers and 0.34, we get the equation 2x + 0.34; now we set it equal to 2, 2x + 0.34 = 2. 

To solve, 1st subtract 0.34 on both sides to get 2x = 1.66. Now divide by 2 on both sides to get x = 0.83. 

So your decimals are 0.34, 0.83, and 0.83
