Question

3×(_1)=_3 how is this possible ​

Answer 1

Step-by-step explanation:

Let the missiong number be a

3 x (a x 1) = a x 3

L.H.S

3 x (a x 1)

= 3 x a1 (constant x variable = constant times variable)

= 3 x 1a = 3 x a ( 1 times variable = variable)

= 3a

R.H.S

a x 3

= a3 (constant x variable = constant times variable)

= 3a

∴ L.H.S = R.H.S Proved
