Question

Arvind wrote 15 1/3 pages of his story on Saturday and 17 7/12 pages on Sunday .How many more pages did he write on Sunday than on Saturday?

Answer 1

The number of pages Arvind wrote more on Sunday than on Saturday is $\frac{27}{12} = 2 \frac{3}{12}.$

Given:

Number of pages Arvind wrote on Saturday = $15 \frac{1}{3}$

Number of pages Arvind wrote on Sunday = $17 \frac{7}{12}$

To find: How many more pages did he write on Sunday than on Saturday?

Solution:

Step 1: Convert the given mixed fraction into an improper fraction:

Number of pages Arvind wrote on Saturday = $15 \frac{1}{3} = \frac{15 \ \times \ 3 \ + \ 1}{3} = \frac{46}{3}$

Number of pages Arvind wrote on Sunday = $17 \frac{7}{12} = \frac{17 \ \times 12\ +\ 7}{12} = \frac{211}{12}$

Step 2: Find a number of pages Arvind wrote more on Sunday than on Saturday:

Subtract the Number of pages Arvind  wrote on Saturday from the Number of pages Arvind  wrote on Sunday:

Number of pages Arvind wrote more on Sunday than on Saturday $= \frac{211}{12} - \frac{46}{3}$

$= \frac{211}{12} - \frac{46 \times 4}{3 \times 4} \\\\= \frac{211}{12} - \frac{184}{12} \\\\= \frac{211 - 184}{12} \\\\= \frac{27}{12} \\\\= 2 \frac{3}{12}$

Hence, a number of pages Arvind wrote more on Sunday than on Saturday is $\frac{27}{12} = 2 \frac{3}{12}$.
