Any irrational number added to 0.5 will produce an irrational number.
10056÷23 gives 437 as quotient and 5 as remainder. Dividend-remainder= divisor× quotient so 10056-5=23×437 gives 10051.our question is least no should be added to 10056 which is divisible by 23. Check next possibility 23×438 gives 10074. Now 10056+18= 10074. Therefore 18 is the least number should be added to 10056 to get a number divisible by 23

A natural number is doubled when added to its reciprocal. Find that number!
any odd number is of the form 2n +1 so (2a+ 1) + (2b +1) gives 2(a + b) +2 , ie an even number plus 2 which is another even number
To find the number that must be added to 38 to make 100, you would subtract 38 from 100. This calculation gives you 62. Therefore, 62 must be added to 38 to make 100.
