SOLUTION

TO CHOOSE THE CORRECT OPTION

Given that a, b and c are whole numbers, which of the following shows the associative rule

1. a × ( b × c ) = ( a × b ) × c

2. a + (b×c) = (a×b)+c

3. a × (b+c) = (a+b) ×bc

4. a × (b−c) = ( a−b) × c

EVALUATION

Here it is given that a, b and c are whole numbers

Now associative property under multiplication states that

a × ( b × c ) = ( a × b ) × c

Again associative property under addition states that

a + ( b + c ) = ( a + b ) + c

FINAL ANSWER

Hence the correct option is

1. a × ( b × c ) = ( a × b ) × c
