Is 5/12 greater than 3/4

Answers

$(5)/(12) \hbox{ and }(3)/(4)=(3 * 3)/(4 * 3)=(9)/(12) \n \n5<9 \Rightarrow (5)/(12) < (9)/(12) \Rightarrow (5)/(12) <(3)/(4)$

No, 3/4 is greater than 5/12.

5/12 is not greater than 3/4 because 3/4 is only 1/4 away from becoming a whole number. On the other hand 5/12 is 7/12 away from becoming a whole number. Hope this helped :)
