I need help with my boys math problem can you help us ?

Question

for each of following use the set of clues to determine the secret number

clue 1 the number has two digits

clue 2 the number has 13 as a factor

clue 3 the sum of the digits of the number is 11

could you explain how to do it as well so my child can learn to do it him self as i don't know how to solve it either

Answer 1

-24+13= 11

-24 is an integer number that has two digit plus 13= 11

Answer 2

1) Let the first digit be X, and the other digit be Y.

2) So lets name all the multiples of 13 = 13, 26, 39, 52, 65 etc...

3) X + Y = 11

So let X be 1 and Y be 3. So 1 + 3 = 4, but its not 11.

Neither is it 26 because 2 + 6 = 8

And 3 + 9 = 11, 5 + 2 = 7.. but 6 + 5 = *11*.

Therefore, 65 is your answer.

Answer 3

first, list all two digit numbers that have 13 as a factor.

13, 26, 39, 52, 65, 78, 91

second, find which of these numbers has digits that add up to 11.

the answer would be 65.

Answer 4

ok! i say you cant really tell the answer from clue 1 so move to number 2, that gives you a lil info. but clue 3.. what makes 11? 6+5=11. so i say 65. but you have ot make sure your guess fits all 3 clues right? so , therefore 65 divided by 13 = 5. so that shows that my answer 65 has  a factor of 13, and clue one say it had 2 digits, well 65 is two digits so my answer is 65.. but i solved it critically so you mite wannt ot email the teacher dad and the child should like so try it , i mean its not a equation to it, just critical thinkin... oyeh you lose a dad point ! lol
