If a,b and c are whole numbers, then a+(b+c)=(a+b)+c. This property is called
If a + b = c and a × b = c , where a and b are whole numbers, then c is also a whole number. This follows which of the properties of whole numbers?
For four numbers a, b, c, d if a : b = c : d, then a : c = b : d. Which property of proportion is this?
If (a×b) × c = a × (b ×c), where a,b and c are all whole numbers,then it follows which property?
