If 6a divided by 2 equals 12 then A equals
Since '305' is an ODD Number, it is NOT divisible by '2' However, since it ends in '5' it is divisible by '5'. NB EVEN numvers ends in 0,2,4,6,8 ODD Numbers end in 1,3,5,7,9 since 305; ends in ;5; it is an ODD Numbers. Here are some 'tricks to remember. #1 ALL Even numbers are divisible by '2'. #2 All numbers ending in '--5' or '--0' are divisible by '5'. #3 All numbers ending in '---0' are divisible by '2;, & 10.; #4 If the sum of the digits of numbers add to '9', then it is divisible by '9'. e.g. 144 ; 1 + 4 + 4 = 9 . So ;144; is divisible by '9' #5 This only leaves '3' and '7' were you have to fully test the divisibility of a numbers. #6 To test for '11' . Then a number such as 132 will divide by '11' because if the sum of the two end number is equal to the middle number, then it will divide by ;11; e.g. ''1' & '2' added make '3' , which is the middle number of '132' . 154 is another number as is 297.
