Question

There are 7 blue kites and 7 red kites. The image below shows the total number of blue and red balls. The items of which color are fewer in number: blue or red? Identify the correct equations representing each type of colored item.

• A. Red items; Blue items: 7 + 8 = 15, Red items: 7 + 9 = 16
  
• B. Red items; Blue items: 7 + 8 = 14, Red items: 7 + 9 = 17
  
• C. Blue items; Blue items: 7 + 9 = 16, Red items: 7 + 8 = 15
  
• D. Both red and blue items are the same in number; Blue items: 7 + 8 = 15, Red items: 7 + 9 = 15
  

Answer 1

The correct option is A Red items; Blue items: 7 + 8 = 15, Red items: 7 + 9 = 16
