⟹ Find the value of x in the following proportion:

• 45 : x :: 25 : 35

$\star\large\mathfrak{\underline{ \underline{ solution }}}$

The Equation given here is :

• 45 : x :: 25 : 35

We can also write 45 : x :: 25 : 35 as = $\frac{45}{x} = \frac{25}{35}$

$\rm\color{blue}{Now \: solving \: this \: equation :) }$

$\sf \implies \frac{45}{x} = \frac{25}{35 } \\ \\ \sf \implies \: x = \frac{45 \times 35}{25} \\ \\ \sf \implies \: x = 56$

The value of x is 56
