Question

if the 40% of a number is 18 so what is the actual number?​

Answer 1

Answer:

=》Let the actual number be 'x'

=》

$x \times \frac{40}{100} = 18 \\ x \times \frac{2}{5} = 18 \\ x \times 2 = 18 \times 5 \\ 2x = 90 \\ x = \frac{90}{2} \\ x = 45$

=》Therefore the actual number is 45

Answer 2

Step-by-step explanation:

let the number be x,

$\Large\rm\purple{(\frac{40}{100})x \:=\: 18}$

$\large\rm{40x \:=\: 1800}$

$\large\rm{x \:=\: (\frac{1800}{40})}$

$\large\rm\green{x \:=\: 45}$
