$\frac{1}{2}$
Work Step by Step
0.5
The digits to the right of the decimal point, 5, are the numerator of the
fraction. The denominator is 10 for tenths because the rightmost digit is in the tenths place.
i.e. $\frac{5}{10}$
= $\frac{5\div5}{10\div5}$ (Divide both numerator and denominator by 5)
= $\frac{1}{2}$ (Lowest Terms)
