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

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

14,35:(0,5+0,125)

=14,35:0,625

=22,96

= 14,35 : (0,5 + 0,125)
= 14,35 : 0,625

= 22,96

22,96
Chúc bn hk tốt
