Question

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? Explain how you know.

Answer 1

2 - 0.34 = 1.66

0.96 + 0.7 = 1.66

Holland could have used 0.96 and 0.7 (or any other 2 decimals that add up to 1.66).

Answer 2

The two other numbers could be 0.83.

First, do the equation 2 - 0.34 = 1.66.

Next, divide 1.66 ÷ 2 = 0.83.

Finally, add 0.83 + 0.83 + 0.34 = 2.

So the two other decimals Holland could do is 0.83.
