Total number of Bananas = 18
Number of Bananas that are left = 10
Percentage of Bananas that are left = x
Mathematically, x can be expressed as:
[tex]x= \frac{10}{18} * 100 \\ \\
\frac{x}{100}= \frac{10}{18} \\ \\
\frac{x}{100}= \frac{5}{9} [/tex]
Thus the correct percentage of number of bananas that are left is expressed by option c.
