Question

Tính bằng cách thuận tiện nhất:

a. 4345 : 126 + 3845 : 126                         b. 24563 : 126 – 12215 : 126 

Answer 1

\(a.=\left(4345+3845\right):126\\ =8190:126=65\\ b.=\left(24563-12215\right):126\\ =12348:126=98\)

Answer 2

\(a,4345:126+3845:126=\left(4345+3845\right):126=8190:126=65\\ b,24563:126-12215:126=\left(24563-12215\right):126=12348:126=98\)

Answer 3

a.=(4345+3845):126=8190:126=65b.=(24563−12215):126=12348:126=98

Answer 4

a. = ( 4345 + 3845 ) : 126

= 8190 : 126 = 65

b . = ( 24563 − 12215 ) : 126

= 12348 : 126

= 98

Answer 5

tôi tương bn học rồi

Answer 6

a,4345:126+3845:126=(4345+3845):126=8190:126=65

b,24563:126−12215:126=(24563−12215):126=12348:126=98

Answer 7

a , 4345 : 126 + 3845 : 126 = ( 4345 + 3845 ) : 126 = 8190 : 126 = 65

b , 24563 : 126 − 12215 : 126 = ( 24563 − 12215 ) : 126 = 12348 : 126 = 98
