Answer 2

Step-by-step explanation:

a) 853 + 908 + 447

= 853 + 447 + 908

(since, according to commutative property

908+447= 447+908)

= 1300+908

= 2208

so, 853+908+447= 2208

b) 1783 + 347 + 117

= 1783 + 117 + 347

(since, according to commutative property

347+117= 117+347)

= 1900+347

= 2247

so, 1783+347+117= 2247
