hey friend your answer in pictures i hope it will be helpful to you

thank you
$let \: x \: be \: the \: tota \: no. \: of \: pages \\ \\ pages \: read \: = \frac{4}{9} \: \\ \\ remaining \: pages \: = 30 \\ \\ remaining \: pages \: in \: fraction \: \\ = \frac{9}{9} - \frac{4}{9} \\ \\ = \frac{5}{9} \\ \\ therefore \: the \: total \: no. \: of \: pages \: \\ = \frac{5}{9} \times x = 30 \\ \\ x = 30 \div \frac{5}{9} \\ \\ x = 30 \times \frac{9}{5} \\ \\ x = 54 \: pages$

Answer 2

Here is your answer, Friend :))

Let x be the total number of pages.

pages read = 4/9

Remaining Pages = 30 = 5/9 of book remaining

=5/9 * x = 30

x = 30 * 9/5

x = 54

Therefore, The total number of pages in the book are 54 pages
