Result

x=

Yes

No

Step-by-step explanation:

$$\begin{gathered} r=3{\displaystyle \frac{1}{2}}=3+{\displaystyle \frac{1}{2}}={\displaystyle \frac{3\cdot 2+1}{2}}={\displaystyle \frac{7}{2}}=3.5\text{ cup } \\ a={\displaystyle \frac{7}{8}}=0.875\text{ cup } \\ b=2{\displaystyle \frac{1}{2}}=2+{\displaystyle \frac{1}{2}}={\displaystyle \frac{2\cdot 2+1}{2}}={\displaystyle \frac{5}{2}}=2.5\text{ cup } \\ s=a+b=0.875+2.5={\displaystyle \frac{27}{8}}=3\frac{3}{8}=3.375\text{ cup } \\ s<r \\ x=0 \end{gathered}$$
