Rút gọn:

A = 4116 - 14/10290 - 35                                B = 2929 - 101/2.1919 + 404

Answer 1

A=4116-14/10290-35
=[14 x ( 294 -1 )]/[35 x (294-1)]
= 14/35

B =2929-101/2.1919+404
= [101 x (291-1)] / [101 x 38 + 101 x 4)]
= [ 101x (29 -1)] / [ 101 x (38+4)
= (29-1) / (38+4)
= 28/42 = 2/3

Answer 2

A=4116-14/10290-35=14.294-14.1/35.294-35.1=14.(291-1)/35.(294-1)=14/35=14:7/35:7=2/5

B=2929-101/2.1919+404=101.29-101.1/2.19.101+4.101=101.(29-1)/101.(2.19+4)=28/42=28:14/42:14=2/3

Answer 3

de et ngu nhu bo y ko lam dc 

Answer 4

4116-14/10290-35=4102/10255=2051.2/2051.5=2/5

Answer 5

A=4116-14/10290-35=14×(294-1)/35×(294-1)=14/35=2/5

B=2929-101/2×1919+404=29×101-101/38×101+404=101×(29-1)/101×(38+4)=28/42=2/3
