Final answer:
To create green paint, So-hee mixes yellow paint and blue paint in specific ratios by volume.
Step-by-step explanation:
When So-hee mixes yellow paint and blue paint by volume to make green paint, they are combining different volumes of each color to achieve the desired shade of green.
To complete the table with the same ratio of yellow paint to blue paint, we need to find the volumes of yellow and blue paint that are mixed together to create green paint.
For example, if we mix 2 volumes of yellow paint with 3 volumes of blue paint, we get a green paint that represents a ratio of 2:3.
