write the largest number from the one two and three digit
Find all natural numbers having two digit , knowing that twice the units digit 1 more than the ten digit , and if we write that two digits in reverse order, we get a new number which is 27 less than the old one
Tell the numbers to find are \(\overline{ab}\)
\(\Rightarrow\left\{{}\begin{matrix}2b-a=1\\\overline{ab}-\overline{ba}=27\end{matrix}\right.\)
=> 10a + b - 10b - a = 27
=> 9a - 9b = 27
=> a-b = 3
=> a = b + 3
=> 2b - 1 = b+3
=> 2b - b = 3 + 1
=> b = 4
=> a = \(2\cdot4-1=7\)
So he number to find is 74
using each of a digit 3,4,5 and 6 exactly once to form two 2 digit numbers .what is the different between the largest possible product and the smallest possible product of two such number
Hai số lớn nhất là 65; 64
Hai số nhỏ nhất là 34 ; 35
Hiệu là : 65 x 64 - 35 x 34 = 2970
nếu đúng tk cho mk nha
34; 35; 36; 43; 45; 46; 53; 54; 56; 63; 64; 65.
The largest number is 65.
The smallest number is 34.
in a 4-digit number, the ones digit is the possible largest number, the hundreds digit is the smallest odd number and the tens digit is 1 more than the hundreds digit. The thousands digit is the sum of the hundreds and the tens digit. Find the number

How many natural numbers are there between 100 and 999 that unit-digit and tens-digit equal hundreds-digit ?
What is the difference between the largest and the smallest possible distinct 4-digit number that you can make from four digits 0, 4, 2 and 3?
Dịch đề bài: Hiệu (hay khoảng cách) của số lớn nhất và số nhỏ nhất có bốn chữ số khác nhau được lập ra từ 4 chữ số 0, 4, 2 và 3?
Giải:
Số lớn nhất có 4 chữ số khác nhau được lập từ 4 chữ số đó là: 4320
Số bé nhất có 4 chữ số khác nhau được lập từ 4 chữ số đó là: 2034
Vậy hiệu (hay khoảng cách) của hai số đó là:
4320 - 2034 = 2286
Đáp số: 2286
Lesson 1: I ask her, "How old are you this year?" "One sixth of a six-year-old is six years old," she said. How old are you?
Lesson 2: The sum of the two numbers is 873. The large number is the product of the number of the smallest and the largest number with a digit. Find two of them.
Lesson 3: How old are you? Dad more than 30 years old. Calculate the age of each person
sorry i don't have any time to tell you the answer .Anyway you should use your mind to do that
