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+14,35+9,25= 28,87

6,4+18,36+52=76,76

= 28,87

= 28,87

28,87

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

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

14,35 × 63 + 14,35 × 36 + 14,35

= 14,35 x 63 + 14,35 x 36 + 14,35 x 1

= 14,35 x ( 63 + 36 + 1 )

= 14,56 x 100

= 1456

\(14,35\times63+14,35\times36+14,35\)

\(=14,35\times\left(63+36+1\right)\)

\(=14,35\times100\)

\(=1435\)

1456 nhé

a) 14,35 x 63+37 x 14,35

= (63+37) x 14,35

= 100 x 14,35 = 1435

b ) 4/3 x 699 x 0,75

= 4/3 x 699 x 3/4

= 4/3 x 3/4 x 699

= 1x699 = 699

 a,   14,35 nhân (37 +63) =1435

a ra 1435

b ra 699

good luck
