Question

Which is bigger, 7/10 or 3/4?

Answer 1

`Method\ \#1:\\\\(7)/(10)=0.7\\\\(3)/(4)=0.75\\\\0.7 < 0.75\ therefore\ bigger\ is\ (3)/(4)\\------------------------`


`Method\ \#2\\\\Find\ LCD\ of\ (7)/(10)\ and\ (3)/(4)\to\ LCD((7)/(10);\ (3)/(4))=20\\\\(7)/(10)=(7\cdot2)/(10\cdot2)=(14)/(20);\ (3)/(4)=(3\cdot5)/(4\cdot5)=(15)/(20)\\\\(14)/(20) < (15)/(20)\ therefore\ bigger\ is\ (3)/(4)`
