b) 20
c) 16
d) 18

Answer 1

Answer:

$\huge \sf \underline{given \ \: : }$

$\blue \bull \sf \: \: \: \: \frac{3}{4} \: \: = \: \: \frac{x}{24}$

$\huge \sf \underline{ to \: find\ \: : }$

$\blue \bull \sf \: the \: value \: of \: \: (x)$

$\huge \sf \underline{solution \ \: : }$

$\sf \to \frac{3}{4} = \frac{x}{24}$

$\sf \to x = 24 \times \frac{3}{4}$

$\sf \to x = 6 \times 3$

$\red{ \sf{ \to x = 18}}$

Answer 2

Given:

The number = 3/4

Its equivalent = x/24

To Find:

The value of x

Solution:

Since the number is equivalent it means that both the values are identical. Such values are denoted by the " = " sign.

Defining the equation to find the value of x -

3/x = x/24  

Solving, the equation -  

x = 24 x 3/4

x = 6 x 3

x = 18

Answer: The value of x is d) 18.
