Chúc bn làm bài tốt nha!!!

a) 5,27+14,35+9,25

= 19,62+9,25

= 28,87

b) 6,4+18,36+52

= 24,76+52

= 76,76

c) 0,75+0,09+0,8

= 0,84+0,8

= 1,64

k mình nha

Chúc bạn học giỏi nhé

5,27 : 0,25 + 5,27 : 0,5 +5,27 : 0,2

= 5,27 x 4 + 5,27 x 2+ 5,27 x 5

= 5,27 x (4+2+5)

= 5,27 x 11

= 5,27 x 10 + 5,27

= 52,7 + 5,27

= 57,97

A)=19,62+9,25

=28,87

B)=24,76+52

=76,76

C)52,99+7,15

=60,14

Đ)=0,84+0,8

=1,64

\(x\times1,23+x\times5,27=227,5\)

\(x\times\left(1,23+5,27\right)=227,5\)

\(x\times6,5=227,5\)

\(x=227,5\div6,5\)

\(x=35\)

15,7

a ) thiếu đề
