Question

conforme os exemplos vistos na aula determine o valor de cada termo nas proporções​

Answer 1

Resposta:

A)$\frac{X}{3} =\frac{10}{6} =$ multiplica cruzado

  6.x=3.10

 6x=30

   x=$\frac{30}{6}$

  x=5

B)$\frac{x}{4} =\frac{91}{52}$= multiplica cruzado

52.x=4.91

   52x=364

     x=$\frac{364}{52}$

     x=7

c)$\frac{x}{4} =\frac{18}{21}$

21.x=18.7

21x=126

x= $\frac{126}{21}$

x=6

d)$\frac{x}{105} \frac{2}{30}$= multiplica cruzado

30.x=105.2

30x=210

x=$\frac{210}{30}$

x=7

e)$\frac{x}{8} =\frac{36}{32}$= multiplica cruzado

32.x=8.36

32x=288

x=$\frac{288}{32}$

x=9

f)$\frac{x}{3}= \frac{128}{48}$= multiplica cruzado

48.x=3.128

48x=384

x=$\frac{348}{48}$

x=8
