Question

The picture below shows the number of fish in the fish tank. A few more fish are added, making the total as $15$. Identify the addition equation that shows the total number of fishes. How many more fish are added to the total to be $15$?

• A. $8+3=11;4$
• B. $10+4=14;3$
• C. $11+4=15;4$
• D. $4+7=12;3$

Answer 1

The correct option is C $11+4=15;4$

Solution: Option B
Say:
Let us read the question and observe the image.

Ask:
How many fish can we see in the fish tank?
Ans: $11$

What do we need to find out?
Ans: We need to find out how many more fish are added that makes the total number of fish in the tank $15$.

How much do we add to $11$ to make it $15$?
Ans: $4$

What will be the equation that will represent the total number of fish in the fish tank?
Ans: $11+4=15$

How many more fish are missing in the image?
Ans: $4$

Hence, Option B is the correct answer.

WB: If required, use the whiteboard to represent the problem as shown and write the addition equation.
