When the digits of a two digit numbers are reversed the number increases by 27?
So the number is 10*a + b. The digits are reversed when 27 is added to it. Therefore for all the numbers 14 , 25 , 36 , 47 , 58 and 69 the digits are reversed when 27 is added.
When the digits of a two digit numbers are reversed number obtained is 9 less than?
The number is 27.
How many two digit numbers are divisible by the product of digits?
We have now considered all the potential values of m. Hence we conclude that the only 2-digit positive integers which are divisible by both the sum and product of their digits are 12, 24, and 36.
When you reverse the digits in a certain two digit number you decrease its value by 54 find the number if the sum of its digits is 6?
1 Expert Answer Use X and Y for the digits, with X being the “tens” digit. We’re also told that reversing the digits decreases the value by 54. Therefor, the number is 60.
What is the sum of reversed 2-digit numbers?
27 + 72 = 99. The sum of the digits in the 2-digit number determines the sum of the reversed numbers in the following way: If the sum is 6 the answer is 66 (24 + 42 = 66; 15 + 51 = 66 etc) If the sum is 8 then the sum of the reversed numbers is 88.
What is the difference between 36 and 2 digits?
In a number of two digits, unit’s digit is twice the tens digit. If 36 be added to the number, the digits are reversed. The number is In a number of two digits, unit’s digit is twice the tens digit. If 36 be added to the number, the digits are reversed.
How do you introduce a reversed 2 digit problem?
Introduce the problem – you could do this by writing 2 reversed 2-digit numbers eg 14 and 41. Ask the students what they can tell you about the 2 numbers. If they identify that the digits have swapped places then introduce the problem.
What happens to the place value when you reverse a number?
As numbers are ‘reversed’ they swap places. (eg. 41 to 14) It is therefore important to discuss what is happening to the place value of the numbers. Take any 2-digit number. Reverse the digits to make another 2-digit number. Add the two numbers together.
