The closest number to 340 that can be made using the given cards (3, 5, 6, 4, and DECIMAL POINT) is 340.5.
To find the closest number to 340 that can be made using the given cards (3, 5, 6, 4, and DECIMAL POINT) while using each card only once, we can approach the problem systematically.
1. Start by considering the possible positions for the decimal point in the number. In this case, we have one decimal point card, so we can place it after any of the digits (3, 5, 6, or 4).
2. After placing the decimal point, we can arrange the remaining digits to form different decimal numbers. For example, if we place the decimal point after the 4, we can form the number 340.5.
3. Similarly, we can form other decimal numbers by placing the decimal point in different positions. For instance, if we place the decimal point after the 3, we get 34.05.
4. We can continue this process and find all possible decimal numbers using the given cards.
5. Next, we can compare these decimal numbers to determine which one is closest to 340.
6. To compare, we calculate the difference between each decimal number and 340.
7. After comparing the differences, we can find the decimal number that has the smallest difference, which will be the closest to 340.
8. For example, if we calculate the difference between 340.5 and 340, we get 0.5. If we calculate the difference between 34.05 and 340, we get 305.95.
9. By analyzing the differences, we can determine the decimal number that is closest to 340.
In summary, the closest number to 340 that can be made using the given cards (3, 5, 6, 4, and DECIMAL POINT) is 340.5.
The question probable may be:
