1. Which of the following is the lowest ratio ?

A. 7 : 15

B. 15 : 23

C. 17 : 25

D. 21 : 39

Solution:

\begin{aligned} \Rightarrow 7 : 15 = \frac{7}{15} = 0.466 \\ \Rightarrow 15 : 23 = \frac{15}{23} = 0.652 \\ \Rightarrow 17 : 25 = \frac{17}{25} = 0.68 \\ \Rightarrow 21 : 39 = \frac{21}{39} = 0.538 \end{aligned}

Clearly, 7 : 15 is the lowest
