Question

tính bằng cách thuận tiện nhất:

49, 358 + 32,16 + 29,452 - 9, 358 + 2,16 + 0, 548 

Answer 1

=(49,358-9,358)+(32,16+2,16)+(29,452+0,548)

=30+40+34,32

=104.32

Answer 2

\(49, 358 + 32,16 + 29,452 - 9, 358 + 2,16 + 0, 548 \)

\(=(49,358-9,358)+(32,16+2,16)+(29,452+0,548)\)

\(=30+40+34,32\)

\(=70+34,32\)

\(=104,32\)
