7/8у=1 1/4; 8/9х=2/9;5/9х=1; 4/7х=16; х÷8/16=32/45; 7 1/5÷х=9/10; 3 3/5÷з=1 4/5; х÷5/6=12/13; 5÷х=1 1/14

Answer 1

Ответ:

Пошаговое объяснение:

7/8у=1 1/4;

у=1 1/4:7/8

y=5/4*8/7

y=10/7=1 3/7

8/9х=2/9;

x=2/9*9/8

x=1/4

5/9х=1;

x=1*9/5

x=9/5=1 4/5

4/7х=16;

x=16*7/4

x=28

х÷8/16=32/45;

x=32/45*8/16

x=16/45

7 1/5÷х=9/10;

x=9/10:7 1/5

x=9/10*5/36

x=1/8

3 3/5÷з=1 4/5;

z=1 4/5:3 3/5

z=9/5*5/18

z=1/2

х÷5/6=12/13;

x=12/13*6/5

z=72/65=1 7/65

5÷х=1 1/14

x=1 1/14:5

х=15/14*1/5

x=3/14

Answer 2

To solve these equations, I'll break them down one by one:

1. $\frac{7}{8}y = \frac{1}{4}$

   To solve for $y$, multiply both sides by $\frac{8}{7}$:

   $y = \frac{1}{4} \times \frac{8}{7} = \frac{2}{7}$

2. $\frac{8}{9}x = \frac{2}{9}$

   To solve for $x$, multiply both sides by $\frac{9}{8}$:

   $x = \frac{2}{9} \times \frac{9}{8} = \frac{1}{4}$

3. $\frac{5}{9}x = 1$

   To solve for $x$, multiply both sides by $\frac{9}{5}$:

   $x = 1 \times \frac{9}{5} = \frac{9}{5}$

4. $\frac{4}{7}x = 16$

   To solve for $x$, multiply both sides by $\frac{7}{4}$:

   $x = 16 \times \frac{7}{4} = 28$

5. $\frac{x}{\frac{8}{16}} = \frac{32}{45}$

   Simplify the left side by multiplying $x$ by $\frac{16}{8}$:

   $2x = \frac{32}{45}$

   Now, divide both sides by 2:

   $x = \frac{32}{45} \div 2 = \frac{16}{45}$

6. $\frac{7\frac{1}{5}}{x} = \frac{9}{10}$

   To solve for $x$, multiply both sides by $\frac{10}{9}$:

   $x = 7\frac{1}{5} \times \frac{10}{9} = 8$

7. $\frac{3\frac{3}{5}}{z} = 1\frac{4}{5}$

   To solve for $z$, multiply both sides by $\frac{5}{3\frac{3}{5}}$:

   $z = 1\frac{4}{5} \times \frac{5}{3\frac{3}{5}} = 2$

8. $\frac{x}{\frac{5}{6}} = \frac{12}{13}$

   Simplify the left side by multiplying $x$ by $\frac{6}{5}$ 0 0
