0.425

NumberToFrac

a = 1000* a/1000

1000* 0.425/1000

Multiply

425/1000

ReduceFrac

a/b=.a /25./.b /25.

17/40

Because 17 and 40 have no common factors, our fraction is as simplified as possible. If there were common factors in the numerator and denominator, we would need to further reduce the fraction.
