Question

I read 1/3 of a book in an hour. How much more of the book will I read in 2 1/5 hours

Answer 1

Answer:

Step-by-step explanation:

To find the number of pages of the book in the given hour:

To find the number of pages in 2 1/5 hours, multiply the number of pages read in 1 hour by 2 1/5 hours.

$\sf \text{ Number of pages read in 2 \dfrac{1}{5} hours = \dfrac{1}{3}*2\dfrac{1}{5} }$

                                                       $\sf = \dfrac{1}{3}*\dfrac{11}{5}\\\\=\dfrac{11}{15}$

$\sf \text{Number of pages read more in 2 \dfrac{1}{5} hours = \dfrac{11}{15}-\dfrac{1}{3} }$

                                                                 $\sf =\dfrac{11}{15}-\dfrac{1*5}{3*5}\\\\=\dfrac{11}{15}-\dfrac{5}{15}\\\\=\dfrac{6}{15}$

Answer 2

Answer:

see below

Step-by-step explanation:

Here is another way

1/3 book / hr   *  2 1/5 hr =

1/3 * 11/5 = 11/15 read in 2 1/5 hr    

1/3is the same as 5 /15          

   11/15 - 5 /15 = 6/15 = 2/5 more read in 2 1/5 hr that 1/3 hr
