To find the two other decimals that, along with 0.34, sum to 2, you can set up the equation:
\( x + y + 0.34 = 2 \)
where \( x \) and \( y \) are the two other decimals.
First, subtract 0.34 from 2:
\( x + y = 2 - 0.34 \)
\( x + y = 1.66 \)
Now, you can choose various values for \( x \) and \( y \) that add up to 1.66. Here are a couple of examples:
-
If you choose \( x = 0.80 \), then: \[ y = 1.66 - 0.80 = 0.86 \] So one possible pair is \( (0.80, 0.86) \).
-
If you choose \( x = 1.00 \), then: \[ y = 1.66 - 1.00 = 0.66 \] So another possible pair is \( (1.00, 0.66) \).
Therefore, two possible pairs of decimals that can be used along with 0.34 to make a total of 2 are \( (0.80, 0.86) \) or \( (1.00, 0.66) \).
