which statement is false?
A: 3.648 reapeating=is rational
B:3 2/13=rational

math 
Reiny
b) 3 1/2 = 7/2
since we just wrote the number as a fraction, it is rational
a) you don't say which digits repeat,
Should we assume the .648 repeats ?
so we have 3.648648648....
= 3 + 648/999
= 3645/999 = 135/37 which is also rational
So neither statement is false
