Question

In the morning, Blake read 1 2/5 pages in his graphic novel. After lunch, he read another 1 1/2 pages. How many pages did he read in all ?​

Answer 1

Add both amount of pages .

`\\ \rm\Rrightarrow 1(2)/(5)+1(1)/(2)`

`\\ \rm\Rrightarrow (7)/(5)+(3)/(2)`

`\\ \rm\Rrightarrow (14+15)/(10)`

`\\ \rm\Rrightarrow (29)/(10)`

`\\ \rm\Rrightarrow 2(9)/(10)`pages

Answer 2

`2 (9)/(10)` pages

Explanation:

`\begin{aligned}1 (2)/(5)+1 (1)/(2)&=(5 * 1+2)/(5)+(2 * 1+1)/(2)\\\\ & =(7)/(5)+(3)/(2)\\\\ & =(7* 2)/(5 * 2)+(3 * 5)/(2 * 5)\\\\ & = (14)/(10)+(15)/(10)\\\\ & = (29)/(10)\\\\ & = 2 (9)/(10)\end{aligned}`
