Which keyword we help you decide which operation to use to solve this following? If K has 5 pencils, what gives one to marry? How many would she have left?
The keyword that helps you decide which operation to use in this problem is "one." This indicates that you need to subtract one pencil from the initial total to find out how many pencils Mary would have left.
To solve this problem, you need to use subtraction. Let's break it down step-by-step:
Step 1: Identify the given information.
The problem states that K has 5 pencils.
Step 2: Identify the operation to use.
The problem asks how many pencils Marry would have left if K gives her one pencil. To find the remaining pencils, we need to subtract the number of pencils given to Marry from the total number of pencils K initially had.
Step 3: Perform the calculation.
We subtract 1 pencil (given to Marry) from 5 pencils (initially had by K).
5 - 1 = 4
Step 4: Answer the question.
If K gives one pencil to Marry, she would have 4 pencils left.
To solve this problem, we need to identify the keywords that indicate the operation(s) to be used. In this case, the keywords are "gives" and "left."
The word "gives" suggests a subtraction operation because it implies that something is being taken away. We can subtract the number of pencils Mary receives from the initial number of pencils K has to determine how many would be left.
Let's break down the problem step by step:
1. Identify the given information:
- K has 5 pencils.
2. Determine the operation:
- The keyword "gives" indicates that we need to use subtraction.
3. Determine the number of pencils Mary receives:
- The problem states that one pencil is given to Mary.
4. Perform the calculation:
- Subtract the number of pencils given to Mary from the initial number of pencils K has: 5 - 1. This gives us the number of pencils Mary would have left.
5. Calculate the result:
- 5 - 1 = 4
Therefore, if K has 5 pencils and gives one to Mary, she would have 4 pencils left.
