Answer 1

Answer:

• 80 pages

Step-by-step explanation:

• Let the number of pages is x
• Tim has read ​30 % of a book

Remaining

• 100% - 30% = 70%

70% of x is 0.7x

• 0.7x = 56
• x = 56/0.7
• x = 80 pages

Answer 2

Answer:

$\bf \huge 80 \: pages$

Step-by-step explanation:

Given that :

• Tim has read 30 % of a book.
• He has 56 more pages to finish.

to find :

• How many pages are there in the book ?

let us assume :

• total pages of book is 100•/•

explanation :

⟼ total book = 100•/•

⟼ Tim has read 30 % of a book.

⟼ 100 - 30 •/• = 70 •/•

⟼ 70 •/• = 56 pages

⟼ 1 •/• = 56 / 70

⟼ 100 •/• = 56 / 70 × 100

⟼ 100 •/• = 56 / 7 × 10

⟼ 100 •/• = 8 × 10

⟼ 100 •/• = 80 pages

∴ tim has 80 total pages in book.
