Question

Скільки разів треба додати до найбільшого одноцифровогочисла найбільше двоцифрове число щоб отримати найбільше трицефрове число?

Answer 1

РЕШЕНИЕ
Наибольшее однозначное число - 9, двузначное - 99, трехзначное - 999.
Можно написать уравнение по условию задачи.
9 + 99*х = 999
99*х = 999 - 9 = 990
х = 990 : 99 = 10 раз - ОТВЕТ

Answer 2

Calculation of the Difference

To determine how many times we need to add the largest one-digit number to the largest two-digit number to obtain the largest three-digit number, we can follow these steps:

1. Find the largest one-digit number: The largest one-digit number is 9. 2. Find the largest two-digit number: The largest two-digit number is 99. 3. Find the largest three-digit number: The largest three-digit number is 999.

Calculation

To calculate how many times we need to add the largest one-digit number to the largest two-digit number to obtain the largest three-digit number, we can subtract the sum of the largest one-digit number and the largest two-digit number from the largest three-digit number.

The calculation can be expressed as follows:

999 - (9 + 99)

Simplifying the calculation:

999 - 108 = 891

Therefore, we need to add the largest one-digit number (9) to the largest two-digit number (99) 891 times to obtain the largest three-digit number (999).

Conclusion

To obtain the largest three-digit number (999) by adding the largest one-digit number (9) to the largest two-digit number (99), we need to perform the addition 891 times.
