Answer:
In general the two other decimals are x and y that satisfy x + y = 1.66 where x ≤ .99 and y ≤ .99
One particular pair would be x = 0.99 and y = 0.67
Step-by-step explanation:
If Holland added three decimals that made a sum of 2 and one of them was 0.34, we are going to name x and y to the other 2 decimals.
We are going to write the equation:

So we have that both the other numbers have to sum 1.66, however, we know both numbers are decimals so neither one of them can be greater than 1.
So this problem has many answers and the answers would be all the numbers that satisfy x + y = 1.66 where x ≤ .99 and y ≤ .99
- For example, if x = 0.99, y would be:
y = 1.66 -0.99 = 0.67.
And our pair of numbers would be 0.99 and 0.67.
y = 1.66 - 0.80 = 0.86
And our pair of numbers would be 0.80 and 0.86
This way, we can find more than 1 answer for the other two decimals.
