Question

Which fraction is larger 1/3, 2/5, 8/15, 13/30. and how do i solve this

Answer 1

`(1)/(3);\ (2)/(5);\ (8)/(15);\ (13)/(30)\\\\Denominators:3;\ 5;\ 15;\ 30\\\\LCD(3;\ 5;\ 15;\ 30)=30\\\\(1)/(3)=(1\cdot10)/(3\cdot10)=(10)/(30)\\\\(2)/(5)=(2\cdot6)/(5\cdot6)=(12)/(30)\\\\(8)/(15)=(8\cdot2)/(15\cdot2)=(16)/(30)\\\\(13)/(30)\\\\(10)/(30) < (12)/(30) < (13)/(30) < (16)/(30)\Rightarrow(1)/(3) < (2)/(5) < (13)/(30) < (8)/(15)`
