My Math Strategy 2

Number 9.

There is a bottle of juice on the table that holds 3.5litres. Ana pours out a cup of juice that is .895ml.

  How much juice is left? 2.605

My strategy would be to use Addition and Subtraction. Like this...

I would add 0.105 to the 0.895. Which would equal 1. L. Then take away 1 from the 3.5. Which equals 2.5. Since I add 0.105 to the 0.895, then I will have to add to the 2.5.

So the answer would be, 2.605.
