Solution:

To find the number of birds still on the tree, we need to subtract the number of birds that flew away from the initial number of birds on the tree.

Given:
Initial number of birds on the tree = 15
Number of birds that flew away = 7

Subtracting the number of birds that flew away from the initial number of birds on the tree, we get:

15 - 7 = 8

Therefore, there are 8 birds still on the tree.

Answer:
The correct answer is option B) 8.

Understanding the Problem
Sarah starts with a total of 10 candies and decides to eat 4 of them. To find out how many candies she has left, we need to perform a simple subtraction.
Calculation Steps
- Initial candies: 10
- Candies eaten: 4
To find the remaining candies, we subtract the number of candies eaten from the initial amount:
- Remaining candies = Initial candies - Candies eaten
- Remaining candies = 10 - 4
Performing the Calculation
- 10 - 4 = 6
So, Sarah has 6 candies left after eating 4.
Conclusion
Therefore, the correct answer to the question "How many candies are left?" is:
- Option 'D': 6
This simple arithmetic problem helps reinforce basic subtraction skills, which are essential for young learners. Understanding how to calculate remaining quantities is a foundational skill for everyday situations.

There were 30 books on a shelf, and 11 books fell off. How many books are still on the shelf?
  • a)
    19
  • b)
    7
  • c)
    39
  • d)
    21
Correct answer is option 'A'. Can you explain this answer?

Given:
Total number of books on the shelf = 30
Number of books that fell off = 11

To find:
Number of books still on the shelf

Solution:
To find the number of books still on the shelf, we need to subtract the number of books that fell off from the total number of books on the shelf.

We can use the following formula to calculate the number of books still on the shelf:

Number of books still on the shelf = Total number of books on the shelf - Number of books that fell off

Substituting the given values into the formula:

Number of books still on the shelf = 30 - 11

Simplifying the expression:

Number of books still on the shelf = 19

Answer:
Therefore, there are 19 books still on the shelf.
