Answer:
Explanation:
A number bond is a simple addition of two numbers that add up to give the sum. By adding ten girls and four boys results fourteen friends. I can tell a story that matches this number bond. There are 14 friends in my karate class. 10 are girls and 4 are boys. 9 of the girls left as we can observe in the above image. Five friends are still there.
