Пошаговое объяснение:

0,5х=1/6*3/8

х=1/16*2/1

х=1/8

---------------------------

0,42х=0,35*6

х=2,1:0,42

х=5

----------------------------

1/3х=7 3/4*1 5/31

х=9*3

х=27

---------------------------------

2,3х=39,1*5

х=195,5:2,3

х=85

----------------------------

1 7/27х=1 7/9*5 2/3

х=272/27*27/34

х=8

Answer 2

Ответ:

1)

$x:\frac{1}{6}=\frac{3}{8} :0,5\\\\x*0,5=\frac{1}{6}*\frac{3}{8} \\\\0,5x=\frac{3}{24}\\ \\x=\frac{3}{24}:0,5\\\\x=\frac{3*1}{24*0,5} \\\\x=\frac{3}{12}\\\\x= 0,25$

2)

$\frac{0,35}{x}=\frac{0,42}{6} \\x *0,42=0,35*6\\0,42x= 2,1\\x=2,1:0,42\\x=5$

3)

$7\frac{3}{4}:\frac{1}{3}=x :1\frac{5}{31} \\\\\frac{1}{3} *x=7\frac{3}{4}*1\frac{5}{31} \\\\\frac{1}{3} x =\frac{31}{4} *\frac{36}{31}\\\\\frac{1}{3}x=\frac{36}{4}\\\\x=9:\frac{1}{3}\\\\x = \frac{9*3}{1} \\x=27$

1)

$\frac{39,1}{x} =\frac{2,3}{5} \\\\2,3x = 39,1*5\\\\2,3x = 195,5\\\\x=195,5:2,3\\\\x = 85$

2)

$1\frac{7}{9}:1\frac{7}{27}=x:5\frac{2}{3} \\\\1\frac{7}{27} x=1\frac{7}{9}*5\frac{2}{3}\\\\\frac{34}{27}x=\frac{16}{9}*\frac{17}{3} \\\\\frac{34}{27}x = \frac{272}{27} \\\\x = \frac{272}{27}:\frac{34}{27} \\\\x=\frac{272}{27} *\frac{27}{34}\\\\x= \frac{8*1}{1*1} \\x=8$
