Answer:
When a number 'x' is divided by another number 'y', the number 'x' is divided into 'y' number of equal parts.
If 'y' divides 'x' without any remainder, then 'x' is evenly divisible by 'y'.
Explanation:
(i) When 21 is divided by 3, 21 is divided into three equal parts and the value of each part is 7.
(ii) When we divide 35 by 5, we get
7 + 7 + 7 + 7 + 7
(iii) When 35 is divided by 5, 35 is divided into 5 equal parts and the value of each part is 7. And also, there is nothing left over in 35.
So, 35 is evenly divisible by 5.
(iv) When 35 is divided by 4, we get
8 + 8 + 8 + 8 + 3
There is remainder 5, when 35 is divided by 3.
So, 35 is not evenly divisible by 4.
Property 2 :
When a number is divided by another number, the division algorithm is, the sum of product of quotient & divisor and the remainder is equal to dividend.
