x nhân 1,2-3,45=4,68
x.1,2=4,68+3,45
x.1,2=8,13
x=8,13:1,2
x=6,775
tick cho mk nha bạn
x . 1,2 - 3,45 = 4,68
x.1,2 = 4,68 + 3,45
x. 1,2 = 8,13
x = 8,13 : 1,2
x = 6,775

21,56 :( 75,6 - 65,8 ) - 0,354 : 2
= 21, 56 : 9, 8 - 0 ,177
= 2,2 - 0,177
= 2 , 023
( 75, 6 - 21,7 ) :4 + 22,82 x 2
= 53 , 9 : 4 + 45 ,64
= 13,475 + 45 ,64
= 59,115
