Final answer:
The number halfway between 0.2 and 0.3 is 0.25, which is found by adding the two numbers and dividing the total by 2.
Step-by-step explanation:
The number halfway between 0.2 and 0.3 can be found by calculating the average of the two numbers. To find the average, you add the two numbers together and then divide by 2.
To show the steps:
- Add 0.2 and 0.3 together: 0.2 + 0.3 = 0.5.
- Divide the sum by 2 to get the midpoint: 0.5 ÷ 2 = 0.25.
Therefore, the number that is halfway between 0.2 and 0.3 is 0.25.
