which statement is false?

A: 3.648 reapeating=is rational
B:-3 2/13=rational

1. 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
