Answer 3

a) 19.64 + 76.34     

= 19.4.16 + 76.34

= 76.16 + 76.34

= 76(16 + 34)

= 76.50

= 4200 

b) 35.12 + 65.13             

= 35.12 + 65.(12 + 1)

= 35.12 + 65.12 + 65

= 12(35 + 65) + 65

= 12.100 + 65

= 1200 + 65

= 1265

c) 136.68 + 16.272

= 126.2.34 + 16.272

= 272.34 + 16.272

= 272(34 + 16)

= 272.60

= 16320
