Adding Fractions Using Visual Models

The video tutorial explains how to determine if the water from two bottles can fit into a third bottle using visual models. The first two bottles are divided into three equal parts, with water filled up to the first line. The third bottle is divided into nine equal parts, with water reaching the second line. The task is to combine the water from all bottles and check if it fits into the third bottle. By dividing the first two bottles into nine parts, each bottle contains three-ninths of water. Adding these to the third bottle, which already has two-ninths, results in eight-ninths of the bottle being filled. The lesson demonstrates adding fractions with unlike denominators using visual models.

What fraction represents the amount of water in the third bottle after combining the water from the first two bottles?
