Elly has 9 sections of her fence that needs panting. It took 1.5 hours to paint three sections. How much longer will it take her to finish panting the fence?

Our working out. 

First we drew 9 fence posts. Then we colored 3 of the fence posts we worked out that it was 1.5 hours. Then we colored another 3 fence posts that also took 1.5 hours then we colored the last three posts which again took 1.5 hours.

After that we did this problem solving.

1.2 + 1.2 +1.2= 4 hours. 

Then we went 3 + 1+ 2. 

We then got our our Answer! 4.2
