Terminating decimals are easy
0.375 is 375/1000, which reduces to 3/8 by dividing out the GCF. Any decimal that ends converts this way — the denominator is a power of ten, and simplification does the rest.
Repeating decimals need algebra
0.333… equals 1/3 exactly, via x = 0.333…, 10x = 3.333…, subtract: 9x = 3. Calculators receive only truncated digits, so this tool finds the best small-denominator match — entering 0.333333 correctly recovers 1/3.
