Question

Given table shows the number of species in each order of living marsupials, by group- What fraction of the Australian marsupial species are from the order Peramelemorphia?

$\frac{24}{211}$
$\frac{24}{235}$
$\frac{24}{334}$
$\frac{235}{334}$

The correct answer is: $fraction numerator 24 over denominator 235 end fraction$

To find fraction of- species from Peramelemorphia order from the total Australian Marsupial species.
∴ to find-

$fraction numerator number space of space Peramelemorphia space order space species space among space Australian space group over denominator number space of space total space Australian space Group space species end fraction$

Step-by-step solution:-
1. Number of Peramelemorphia order species among Australian Group = 24
2. Number of total Australian Group species
= Total of (Microbiotheria + Dasyuromorphia + Peramelemorphia + Notoryctemorphia + Diprotodontia)
= 1 + 71 + 24 + 2 + 137
= 235
∴ Fraction of Australian marsupial species that are from the order Peramelemorphia = $fraction numerator 24 over denominator 235 end fraction$
Final Answer:-
Option B i.e. $fraction numerator 24 over denominator 235 end fraction$ is the correct Option.
