113 : 11
211 : 13
313 : 110
4110 : 13

Answer:- 1

Explanation:-

Solution:

\begin{aligned} 5.5 a = 0.65 b \\ \Rightarrow \frac{55}{10} a = \frac{65}{100} b \\ \Rightarrow 55 a = \frac{65}{10} b \\ \Rightarrow 550 a = 65 b \\ a : b = 65 : 550 \\ = 13 : 110 \end{aligned}

$\eqalign{ & 5.5{\text{a}} = 0.65{\text{b}} \cr & \Rightarrow \frac{{55}}{{10}}{\text{a}} = \frac{{65}}{{100}}{\text{b}} \cr & \Rightarrow 55{\text{a}} = \frac{{65}}{{10}}{\text{b}} \cr & \Rightarrow 550{\text{a}} = 65{\text{b}} \cr & {\text{a}}:{\text{b}} = 65:550 \cr & \,\,\,\,\,\,\,\,\,\,\,\, = 13:110 \cr}$
