Answer:
Total wrapping papers Serena and her grandmother = 51/10
Step-by-step explanation:
Serena's wrapping paper for parents:
sq meters
Grandmother's wrapping paper:
sq meters
In order to determine the combined wrapping papers for both Serena and grandmother, all we need is to add both.
i.e.
Total papers = Serena's wrapping paper + Grandmother's wrapping paper
![=\frac{18}{5}+\frac{3}{2}](https://tex.z-dn.net/?f=%3D%5Cfrac%7B18%7D%7B5%7D%2B%5Cfrac%7B3%7D%7B2%7D)
![=\frac{36}{10}+\frac{15}{10}](https://tex.z-dn.net/?f=%3D%5Cfrac%7B36%7D%7B10%7D%2B%5Cfrac%7B15%7D%7B10%7D)
![\mathrm{Apply\:the\:fraction\:rule}:\quad \frac{a}{c}+\frac{b}{c}=\frac{a+b}{c}](https://tex.z-dn.net/?f=%5Cmathrm%7BApply%5C%3Athe%5C%3Afraction%5C%3Arule%7D%3A%5Cquad%20%5Cfrac%7Ba%7D%7Bc%7D%2B%5Cfrac%7Bb%7D%7Bc%7D%3D%5Cfrac%7Ba%2Bb%7D%7Bc%7D)
![=\frac{36+15}{10}](https://tex.z-dn.net/?f=%3D%5Cfrac%7B36%2B15%7D%7B10%7D)
![=\frac{51}{10}](https://tex.z-dn.net/?f=%3D%5Cfrac%7B51%7D%7B10%7D)
Therefore, total wrapping papers Serena and her grandmother = 51/10
