=3,75(0,25+0,5+0,25)

=3,75x1

=3,75

3,75 x 0,25 + 3,75 x 0,5 + 3,75 x 0,25

= 3,75 x (0,25 + 0,5 + 0,25)

= 3,75 x 1

= 3,75

mn tl hộ e 5p' nữa e phải nộp r

thanks mn nhiều

3.75 : \(\dfrac{1}{4}\) + 3.75 : 0.5 + 3,75 + \(\dfrac{1}{8}\)  + 3,75 x 86

= 3,75 : \(\left(\dfrac{1}{4}+0.5+\dfrac{1}{8}\right)\) + 3,75 x 86

= 3,75 : \(\dfrac{7}{8}\) + 322.5

= 4,3 + 322.5 = 326,8

tích hộ chị nha

3,75:0,5+3,75.7-3,75

=3,75x2+3,75x7-3,75x1

=3,75x(2+7-1)

=3,75x8

=30

3,75:0,5+3,75*7-3,75

=3,75*2+3,75*7-3,75*1

=3,75*(2+7-1)

=3,75*8

=30

tick nha

Lời giải:

$6,25\times x+x+x\times 3,75=49,36$

$x\times (6,25+1+3,75)=49,36$

$x\times 11=49,36$

$x=49,36:11=4,49$

1,25xX+3,75xX=10

Xx(1,25+3,75)=10

Xx5=10

X=10:5

X=2

x.(3,75+6,25)=30

x.10=30

x=30:10

x=3

3,75 × x + 6,25 × x = 30

x. (3,75+6,25)=30

x.10=30

x     =30:10

x     =3

Vậy x=3

5 *x + 3,75 *x + 1,25 *x= 20     

<=>x* (5+3,75+1,25) =20

<=>x* 10 =20

<=>x = 20:10

<=>x =2

\(x\cdot5,25+x\cdot3,75+x=396,8\)

\(x\cdot\left(5,25+3,75+1\right)=396,8\)

\(x\cdot10=396,8\)

\(x=396,8:10\)

\(x=39,68\)

#mon

\(x\times5,25+x\times3,75+x=396,8\)

\(\Rightarrow x\times\left(5,25+3,75+1\right)=396,8\)

\(\Rightarrow x\times10=396,8\)

\(x=396,8\div10\)

\(x=39,68\)

\(x\cdot5,25+x\cdot3,75+x=396,8\)

\(x\cdot\left(5,25+3,75+1\right)=396,8\)

\(x\cdot10=396,8\)

\(x=396,8:10\)

\(x=39,68\)
