Question

Parte de Cálculo: En cada una de las siguientes proporciones, utilizar regla de tres para determinar el valor desconocido

Answer 1

Answer:

x = 4

x = 3

x = 10

x = 3

x = 16

x = 35

Step-by-step explanation:

$\frac{x}{5} :\frac{8}{10}$

x · 10 = 5 · 8

10x = 40

10x ÷ 10 = 40 ÷ 10

x = 4

$\frac{8}{12} :\frac{2}{x}$

x · 8 = 12 · 2

8x = 24

8x ÷ 8 = 24 ÷ 8

x = 3

$\frac{15}{3} :\frac{x}{2}$

x · 3 = 15 · 2

3x = 30

3x ÷ 3 = 30 ÷ 3

x = 10

$\frac{x}{6}:\frac{6}{12}$

x · 12 = 6 · 6

12x = 36

12x ÷ 12 = 36 ÷ 12

x = 3

$\frac{x}{8} :\frac{4}{2}$

x · 2 = 8 · 4

2x = 32

2x ÷ 2 = 32 ÷ 2

x = 16

$\frac{10}{2} :\frac{x}{7}$

x · 2 = 10 · 7

2x = 70

2x ÷ 2 = 70 ÷ 2

x = 35
