(i) 2867 + 986 = 986 + 2867
(ii) 368 x 215 = 215 x 368
(iii) (156 + 273) + 74 = 156 + (273 + 74)
(iv) (86 x 55) x 110 = 86 x (55 x 110)

please answer these questions ​

Answer 1

Answer:

Answer:In (I)

2867+986

=3353

986+2867

=3353

in (II)

368×215

=79120

215*368

=79120

in (iii)

(156+273)

=429+74=503

156+(273+74)

=156+347

=503

in (iv)

(86*55)*110

4730*110

=520300

86*(55*110)

86*6050

=520300

in all the parts we have seen that if we change the order of number the answer will we same

Answer 2

(i) 2867+986 = 986+2867

= 3853 = 3853 True

(ii) 368×215 = 215×368

= 79120 = 79120 True

(iii) (156+273)+74 = 156+(273+74)

= 429+74 = 156+347

= 503 = 503 True

(iv) (86×55)×110 = 86×(55×110)

= 4730×110 = 86×6050

= 520300 = 520300 True
