Since one number is twice the other, the smaller number must be the greatest common factor. Since the greatest common factor is 7, that would make the other number 14. But, 7 is a prime number and has only one prime factor. However, the larger number, 14, has two prime factors. Also, the sum of the two numbers is 21, not 105. So, the information in the problem does not have a solution. Let us ignore the greatest common factor information. Let the smaller number be x. That means the larger number is 2x. x + 2x = 105 => 3x = 105 => x = 35. The two numbers are 35 and 70. The greatest common factor is 35. The smaller number, 35, has only two prime factors.
It's a square number. Square numbers have a factor pair that is the same number twice. When listed, that number occurs once.
The factors of all numbers can be written in pairs. With square numbers, one of those pairs is the same number twice. When listed singly, square numbers have an odd number of factors. All others are even.
half as big example: if $10 then 50% larger = $15 (twice as big = $20)
no one wants to know the answer. its freaking math
Smaller number = x Larger number = 2x x+2x=18. 3x=18 x=6 The numbers are 6 and 12.
The numbers are: 48+22 = 70
Let x = the smaller number2x + 4 = the larger numberx + 2x + 4 = 703x + 4 = 703x = 66x = 22 = the smaller number
If the larger number can be anything more than twice the smaller number, then the two numbers can be:1 + 45 = 463 + 43 = 465 + 41 = 467 + 39 = 469 + 37 = 4611 + 35 = 4613 + 33 = 4615 + 31 = 46
The two numbers are 15 and 31. 15 + 31 = 46.
18 and 38
18 and 38
The smaller number is 8, and the larger one is 21. 8 + 13 = 21 8 + 21(2) = 50
The larger number is 48, the smaller number is 22. 48 is twice the amount of 22 plus 4. If the smaller number is "x" then the larger number is 2x+4. We know that x+2x+4 =70 which ius the same as saying 3x+4 = 70 or 3x = 70-4 = 66 so x, the smaller number is 66/3 =22
There are two consecutive odd numbers such that five times the smaller plus twice the greater is 25. What is the smaller number?
The sum of the sum and difference gives twice the larger number 14 + 4 = 18 → the larger number is 18 ÷ 2 = 9 The difference of the sum and the difference gives twice the smaller number 14 - 4 = 10 → the smaller number is 10 ÷ 2 = 5 → The two numbers are 9 and 5.
