REWRITE USING THE DISTRIBUTIVE PROPERTY, THEN SOLVE 3 X 17

Question

NEED TO KNOW HOW TO SOLVE

Answer 1

17 = 8 + 9

 

3 x 17 can be rewritten as 

 

3(8 + 9) = (3 * 8) + (3 * 9) = 24 + 27 = 51

 

If you multiply 3 x 17, you will also get 51

Answer 2

The obvious sum is 17 = 10+7 (because decimal is a positional number system and there is 1 ten and 7 ones).

 

     3 * 17 = 3 * (10 + 7) = 3*10 + 3*7 = 30 + 21 = 51
