Question

19. The teacher taught 3/5 of the book, Vivek revised 1/5 more on his own. How much does he still have to revise? 12​

Answer 1

Answer:

We know that

Fraction of book teacher taught = 3/5

Fraction of book Vivek revised = 1/5

So the fraction of book Vivek still have to revise = 3/5 – 1/5

= (3 – 1)/ 5

= 2/5

Hence, Vivek still have to revise 2/5 of the book.
