What is number?
" Number is defined as the count of the given quantity as per the given condition."
According to the question,
'x' represents total number of pages of whole book
Number of pages Laurie finished [tex]= \frac{2x}{5}[/tex]
Number of pages Laurie left [tex]= x- \frac{2x}{5}[/tex]
[tex]= \frac{3x}{5}[/tex]
Time required to finish [tex]\frac{2x}{5}[/tex] of pages [tex]= 8[/tex] hours
Time required to finish [tex]x[/tex] pages [tex]= 8 \times \frac{5}{2}[/tex]
Therefore,
Time required to finish the [tex]\frac{3x}{5} = \frac{5}{2}\times 8\times \frac{3}{5}[/tex]
[tex]= 4\times 3[/tex]
[tex]= 12[/tex] hours
