1/2 is .5 that terminates.
1/8th is .125, also terminating.
If you want NONterminating, your looking for things that end up with .33333, .66666, or .999999.
like 1/3, or 2/3.
Anyway. the easy way out of a fraction, is that every fraction is secretly just a division problem.
Ex: 1/2 = .5, But 1 divided by 2 is .5 this works for everything

A fraction will convert to a terminating decimal only if the denominator of the fraction in its reduced form is divisible only by powers of 2 or powers of 5 (or a combination).
0.5 is a terminating decimal and, since it is equal to a half, it is not an integer. A terminating decimal that is not an integer is a rational fraction. However, not all rational fractions are terminating decimals (eg 1/3 = 0.333...).0.1251.2512.5etc.
No, not all fractions can be written as a non-terminating decimal. For instance, 1/3 has infinitely many 3's in the decimal places.
