Extra Example
When Angela was cleaning her refrigerator, she found 2
bottles of catsup. Looking at the label, she noticed that the
capacity of the larger bottle was twice the capacity of the
smaller bottle. She saw that the smaller bottle was 1/3 full
and the larger bottles was 2/3 full. She poured all the
catsup into the larger bottle. How full was the larger bottle
after she poured the smaller into it?
