Question

Fill in the blanks:
(i) Sum of two odd numbers is an ...... number.
(ii) Product of two odd numbers is an ...... number.
(iii) $a\ne 0$ and a × a = a $\Rightarrow$ a = ?

Answer 1

(i) Sum of two odd numbers is an even number. Example: 3 + 5 = 8, which is an even number.
(ii) Product of two odd numbers is an odd number. Example: 5 × 7 = 35, which is an odd number.
(iii) a ≠ 0 and a × a = a
Given: a × a = a
⇒ a = $\frac{a}{a}=1$, a ≠ 0
