What is the value of (100 ÷ 10) ÷ 5? Is it the same as 100 ÷ (10 ÷ 5)? Why? |
|
Answer» (i) (100 ÷ 10) ÷ 5 = 10 ÷ 5 = 2 (ii) 100 ÷ (10 ÷ 5) ≠ (100 ÷ 10) ÷ 5 (iii) Because division of whole numbers are not associative. Also 100 ÷ (10 ÷ 5) = 100 ÷ 2 = 50 But (100 ÷ 10) ÷ 5 = 10 ÷ 5 = 2 = 50 ≠ 2 (i. e) (100 ÷ 10) ÷ 5 ≠ 100 ÷ (10 ÷ 5) |
