Answer:

[tex]2 \frac{9}{10}[/tex] pages

Step-by-step explanation:

[tex]\begin{aligned}1 \frac{2}{5}+1 \frac{1}{2}&=\dfrac{5 \times 1+2}{5}+\dfrac{2 \times 1+1}{2}\\\\ & =\dfrac{7}{5}+\dfrac{3}{2}\\\\ & =\dfrac{7\times 2}{5 \times 2}+\dfrac{3 \times 5}{2 \times 5}\\\\ & = \dfrac{14}{10}+\dfrac{15}{10}\\\\ & = \dfrac{29}{10}\\\\ & = 2 \dfrac{9}{10}\end{aligned}[/tex]
