7. Vadim made a picture graph to show students' favorite colors. This is the key for his graph. Each \( 4=3 \) votes. If 12 students voted for green, how many should there be in the green row of the graph?

Vadim's picture graph represents each image with a value of 3 votes. Since 12 students voted for green, we first need to determine how many images are needed to represent these votes. By dividing the number of votes (12) by the value of each image (3), we find that 12 ÷ 3 = 4. Therefore, there should be 4 images in the green row of the graph. This graph illustrates how to effectively visualize data! Picture graphs are great tools for sharing information in an engaging way, helping everyone quickly understand the preferences of the group without diving deep into numbers. If Vadim ever wants to explain graphs further, he could even bring colors into the discussion—after all, it’s all about finding fun ways to present facts!
