Question

Calcula el valor de x en cada caso
x/5= 5,4
0,75/x= 0,25
x/1,4= 1,2/9
2,7/x= 6,6/14

Answer 1

Explicación paso a paso:

1.

$\frac{x}{5} = 5.4$

$x = 5.4(5)$

$x = 27$

2.

$\frac{.75}{x} = .25$

$.75 = .25x$

$\frac{.75}{.25} = x$

$3 = x$

3.

$\frac{x}{1.4} = \frac{1.2}{9}$

$x = \frac{(1.2)(1.4)}{9}$

$x = \frac{1.68}{9}$

$x = .1866$

4.

$\frac{2.7}{x} = \frac{6.6}{14}$

$6.6x = (2.7)(14)$

$x = \frac{(2.7)(14)}{6.6}$

$x = \frac{37.8}{6.6}$

$x = 5.72$
