Problem Solving

Walt : Use Strategies we already know to solve decimal problems 

On Friday the 7th of August, we learned 
how to use strategies we already know to solve decimal problems. And also we learned how to use decimal number lines.In this Problem, I used a number line. How I solved this problem is that I first drew a number line that started at zero and go's up to four.I know that number lines don't usually start with the number zero. But anyway I started at two point five.Then I jumped one point zero. After that I jumped zero point seven.And then I added two point five to one point seven.And the answer become three point seven.
