No. A number in 'decimal' format is either exact or approximate; there is no reduction needed or possible. A 'decimal' may be approximate if it is irrational (for example, pi, 3.14159...) or repeating (for example, 1/3, which is 0.333333....).
This fraction can't be reduced because it is already in it's simplest form. In decimals this fraction is equal to 1.314285714
terminating decimals and repeating decimals
Decimals don't have factors. If you're trying to reduce the fraction 875/1000, the GCF of 875 and 1000 is 125.
Two of them are terminating decimals and recurring decimals
terminating decimals non terminating decimals repeating decimals non repeating decimals

The answer depends on what you wish to do with decimals.
Terminating decimals are decimals that end, such as, 2.384. Non-terminating decimals that don't end, such as, 0.3333333333.......
You need decimals when you measure and fractions. You need decimals, because to measure and fractions. Also, so whole numbers could exist if there are decimals. There will be no math if there's no decimals.

terminating decimals repeating decimals
Some decimals are. Counting numbers are a proper subset of decimals.
