38,25 - 18,25 + 21,64 - 11,64 + 9,93

= (38,25 - 18,25) + ( 21,64 - 11,64) + 9,93

= 20 + 10 + 9,93

= 30 + 9,93

= 39,93

k mình nha

Chúc bạn học giỏi

Mình cảm ơn

(^_^)

= 20 + 10 + 9,93

= 30 +9,93

= 39,93

38,25 - 11,64 - 18,25 + 9,93 + 21,64

= 38,25 - 18,25 + 21,64 - 11,64 + 9,93

= 20 + 10 + 9,93

= 30 + 9,93

= 39,93

=(38,25 - 18,2) + (21,64-11.64) + 9,93

= 20 + 10 +9,93

= 39.93

= (38,25-18,25)+(21.64-11,64)+9,93

=20+10+9,93

=39,93

bạn nào viết đầy đủ đúng mình sẽ k cho 

thank you

k nha

a: \(60-26,75-13,25\)

\(=60-\left(26,75+13,25\right)\)

\(=60-40=20\)

b: \(38,25-18,25+21,64-11,64+9,93\)

\(=\left(38,25-18,25\right)+\left(21,64-11,64\right)+9,93\)

\(=20+10+9,93=39,93\)

c: \(45,28+52,17-15,28-12,17\)

\(=\left(45,28-15,28\right)+\left(52,17-12,17\right)\)

=30+40

=70

d: \(\left(72,69+18,47\right)-\left(8,47+22,69\right)\)

\(=72,69+18,47-8,47-22,69\)

\(=\left(72,69-22,69\right)+\left(18,47-8,47\right)\)

=50+10

=60
