3,67 x 58,35 + 58,35 x 6,33 + 0,5

= 58,35 x ( 3,67 + 6,33 ) + 0,5

= 58,35 x           10         + 0,5

= 583,5              +              0,5

=                      584

k cho mk nha . Mk kb roi ne

Thanks cậu nhé

a)  4,5 x 5,5 + 4,7 x 4,5

=4,5 x (5,5 +4,7)

=4,5 x 10,2

= 45,9

b) 7,5 x 2,5 x 0,04

=7,5 x (2,5 x 0,04)

=7,5 x 0,1

=0,75

c) 73,5 x 35, 64 ÷ 73,5 x 64,36

=73,5 x(35,64+64,36)

= 73,5 x 100

= 7350

d) 3,12 x 8 x 1,25

=3,12 x (8 x 1,25)

=3,12  x 10

= 31,2

e)6,48 x 11, 25 - 6,48 x 1,25

=6,48 x (11,25 -1,25)

= 6,48x 10

=64,8

f)3,67 x  58,35 + 58,35 x 6,33

=58,35 x (3,67+6,33)

= 58,35x 10

=583,5

You're welcome :))

A) \(4,5\times5,5+4,7\times4,5\)

\(=4,5\times\left(5,5+4,7\right)\)

@Duongg

=20,16 x 58,35 + 20,16 x 53,7 - 20,16 x 12,05

= 20,16 x ( 58,35 + 53,7 + 12,05)

= 20,16 x 124,1

= 2501,856

20,16*58,35+40,32*26,85-20,16*12,05

=20,16*58,35+20,16*2*26,85-20,16*12,05

=20,16*58,35 + 20,16*53,7-20,16*12,05

=20,16*(58,35+53,7-12,05)

=20,16*100

=2016

nhiều quá bn ơi

nhiều quá

A,

0,7.0,25.2,4=0,42

B,

6,33+9,48+3,67+2,52

=(6,33+3,67)+(9,48+2,52)

=10+12

=22

C,

2,5.12,5.0,8.4

=100

D,

20,09-(3,49+6,51)

=20,09-10

=10,09

\(\frac{1}{8}\times58,35+0,125\times41+12,5\%\times0,65\)

\(=0,125\times58,35+0,125\times41+0,125\times0,65\)

\(=0,125\times\left(58,35+41+0,65\right)\)

\(=0,125\times100\)

\(=12,5\)

\(\frac{1}{8}\)x 58,35 + 0,125 x 41 + 12,5% x 0,65

= \(\frac{1}{8}\)x 58,35 + \(\frac{1}{8}\)x 41 + \(\frac{1}{8}\)x 0,65

= \(\frac{1}{8}\)x ( 58,35 + 41 + 0,65 )

= \(\frac{1}{8}\)x 100

= 12,5

a) 0,7 * 0,25 * 2,4

= 0,7 * (0,25 * 2,4)

= 0,7 * 0,6 = 0,42

b) 6,33 + 9,48 + 3,67 2,52

= (6,33 + 3,67) + (9,48 + 2,52)

= 10 + 12 = 22

c) 2,5 * 12,5 * 0,8 * 4

= (2,5 * 4) * (12,5 * 0,8) = 10 * 10 = 100

d) 20,09 - 3,49 - 6,51

= 20,09 - (3,49 + 6,51)

= 20,09 - 10 = 10,09
