\(60-26,75-13,25=60-\left(26,75+13,25\right)=60-40=20\)
60 - 26,75 - 13,25
=60 - (26,75 + 13,25)
=60 - 40
=20
60 - 26,75-13,25=60-(26,75+13,25)=60-40=20
60 - 26,75 - 13,25
= 60 - ( 26,75 + 13,25)
= 60 - 40
= 20
60 - 26,75 - 13,25 = 60 - ( 26,75 + 13,25 ) = 60 - 40 = 20
20 nhá bạn
chúc bạn hóc tốt nhé
