sally had 3 apples she ate 1/2 of one. she gave 1 away. how many apples does she have left.
Sally had 3 apples. She ate 1/2 of one apple, which is equal to 3/2 apples. Therefore, Sally now has 3 - 3/2 = 6/2 - 3/2 = 3/2 apples left.
She then gave one apple away. So, Sally has 3/2 - 1 = 1/2 apple left. Answer: \boxed{\frac{1}{2}}.
To find out how many apples Sally has left, we can follow these steps:
Step 1: Start with the number of apples Sally had, which is 3.
Step 2: Sally ate 1/2 of one apple, which means she ate 1/2 * 1 apple = 1/2 apple.
Step 3: Subtract the number of apples Sally ate from the total number of apples she had: 3 - 1/2 = 3 - 1/2 = 2 1/2 apples.
Step 4: Sally also gave 1 apple away.
Step 5: Subtract the number of apples Sally gave away from the previous result: 2 1/2 - 1 = 1 1/2 apples.
Therefore, Sally has 1 1/2 apples left.
To determine how many apples Sally has left, we need to follow the given scenario step by step.
1. Sally had 3 apples.
2. She ate 1/2 of one apple, which means she consumed half an apple.
To calculate how many apples she has left, we need to subtract half an apple from the initial quantity of apples:
3 apples - 1/2 apple = 2.5 apples
However, the result is not in whole numbers, since Sally can't have half an apple. Therefore, we need to consider the fact that half an apple is equivalent to 1/2. To simplify, we can write the number of apples she has left as a mixed number:
2.5 apples = 2 apples + 1/2 apple
Now, let's move on to the next step:
3. Sally gave 1 apple away.
To calculate how many apples she has left, we need to subtract one apple from the previous result:
2 apples + 1/2 apple - 1 apple = 1 apple + 1/2 apple - 1 apple
Simplifying the expression further, we see that the two positive apples and negative apple cancel each other out, leaving us with:
1/2 apple
Therefore, Sally has 1/2 of an apple left.
