Example 3 Write the additive inverse of the following: (i) (โˆ’7)/19 Additive inverse of (โˆ’7)/19 = = ๐Ÿ•/๐Ÿ๐Ÿ— Check : Number + Additive inverse = 0 L.H.S = Number + Additive inverse = (โˆ’7)/(19 ) + 7/19 = 0 = R.H.S Hence, 7/19 is the additive inverse of (โˆ’7)/19. Example 3 Write the additive inverse of the following: (ii) 21/112 Additive inverse of 21/112 = Check: Number + Additive inverse = 0 L.H.S = Number + Additive inverse = 21/(112 ) + ((โˆ’21)/112) = 0 = R.H.S Hence, (โˆ’21)/112 is the additive inverse of 21/112.
