Question

Please help!! 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

.73 & .93 are two potential answers.

Explanation:

2 - .34 = 1.66

We need to find two other decimals that add up to 1.66.

To do this we divide 1.66 by 2 to get two sets of .83

But since we want two different decimals, we can subtract .10 from one set of .83 and add the same value to the other set to get our remaining two potential decimals of .73 & .93.

Add the decimals together: .34 + .73 + .93 = 2

You could reach other answers by adding a different value to .83 and subtracting the same from the other .83, as long as you don't form a whole number.
