60,14 **** bạn nha

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

20,08+32,91+7,15=60,14

0,75+0,09+0,8=1,64

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

0,75+0,09+0,08=0,92

800,56-348,48=452,08

5,27+14,35+9,25=28,87

Chúc bn làm bài tốt nha!!!

2 ở đâu vậy mn

`[` Tham Khảo `]`

`7,15 : 0,25 + 7,15 : 0,5 + 7,15 xx 5 -7,15`

`= 7,15 xx 4 + 7,15 xx 2 + 7,15 xx 5 -7,15xx1`

`= 7,15 xx (4+2+5-1)`

`=7,15 xx 10`

`=71,5`

\(\text{ }^{\dfrac{\text{7.15}}{\text{0.25}}}\) + \(\dfrac{\text{7.15}}{0.5}\) + 7,15.5 -7,15

=>71,5

`7,15:0,5+7,15xx9-7,15`

`=7,15xx2+7,15xx9-7,15`

`=7,15xx(2+9-1)`

`=7,15xx10`

`=71,5`

\(7,15:0,5+7,15\times9-7,15\\ =7,15\times2+7,15\times9-7,15\\ =7,15\times\left(2+9-1\right)\\ =7,15\times10\\ =71,5\)
