Chúc bạn học tốt nha

889972+96308  =986380

2-5/6=7/6

7/8+3/4=2

726,83-349,67=375,16

bài 1

a) 889972+96408=986380

b) 926,84+549,66= 1476,5

bài 1

a) 889972+96408=986380

b)926,84 + 549,66 = 1476,5

bài 2

a) (679+865)+135 = 679 + (865+135) = 679 +1000=1679

b) 571 + ( 878+429) = (571+429)+878 = 1000 +878 = 1878

Bài 1:

a)986380

b)1476,5

Bài 2)

a)=679+(865+135)

   =679+1000

   =1679

b)=(571+429)+878

   =1000+878

  =1878
