How to graph coordinates (7/5,0) and (0,7/3) on an x,y graph

Answer 1

We have the dominators: 5, and 3.

We must find the LCM (Least Common Multiple) of 5 and 3:

The multiples of 5: 0, 5, 10, 15, 20, 25, ...

The multiples of 3: 0, 3, 6, 9, 12, 15, 18, ...

LCM(5, 3) = 15

`(7)/(5)=(7\cdot3)/(5\cdot3)=(21)/(15)=1(6)/(15)\\\\(7)/(3)=(7\cdot5)/(3\cdot5)=(35)/(15)=2(5)/(15)`

We accept 15 as a unit.

Look at the picture.
