Question

19 sum help please
tomorrow is my paper
please help

Answer 1

Given ,
p : q=1 whole 1/ 3 : 1 whole 1/ 2

p / q = (4 / 3 )/( 3 / 2) = 8 / 9 ---(1)

q: r = 1/ 2 : 1 / 3

q / r =( 1 / 2 )/ (1/ 3 ) = 3 / 2 ----(2)

multiply equation (1) and (2), we get

( p / q ) ×( q / r ) = 8 / 9 × 3 / 2

p / r = 24 / 18 = 4 / 3

hence, p : r = 4 : 3

hope it helps
