GCF-based reduction.
AskSia finds the GCF of numerator and denominator, divides both, and reports the lowest-terms fraction.
Type a fraction or a pair of fractions. AskSia reduces to lowest terms with the GCF shown, scales to any target denominator, finds common denominators when you need to add or compare, and verifies equivalence by cross-multiplication.
Equivalent fractions are different-looking fractions that represent the same value. They come from multiplying or dividing both the numerator and denominator of a fraction by the same non-zero number. For example, 1/2, 2/4, and 3/6 are all equivalent because each can be obtained from another by scaling both parts equally. Two fractions a/b and c/d are equivalent if and only if a*d = b*c (cross-multiplication test).
Reduce, scale, and verify, with every multiplication shown.
AskSia finds the GCF of numerator and denominator, divides both, and reports the lowest-terms fraction.
To get a target denominator, AskSia multiplies numerator and denominator by the same factor and shows the arithmetic.
For adding fractions, AskSia finds the LCD and scales each fraction to it before adding.
Two fractions a/b and c/d are tested for equivalence by computing a*d and b*c and comparing.
Equivalence shown as bars divided into different numbers of parts but covering the same shaded area.
Fractions with variables, like (x+2)/(x^2-4), get reduced by factoring and canceling common factors.
Type, paste, photograph, or speak the fraction or pair. AskSia identifies numerator and denominator.
Reduce to lowest terms, scale to a target denominator, find common denominators, or verify equivalence of a pair.
Reduced or scaled fraction with the multiplier shown. Cross-multiplication verification for any pair.

Reduce 12/18 to 2/3 by dividing both by GCF 6. AskSia shows the GCF computation and the division.
Need common denominators. AskSia finds the LCD, scales each fraction, and combines.
Is 3/7 less than 5/12? Cross-multiply: 3*12 = 36, 5*7 = 35. So 3/7 > 5/12.
Express 2/5 as a fraction with denominator 20. Multiply both parts by 4: 8/20.
(x^2 - 4)/(x + 2) simplifies to x - 2 (with x not equal to -2). AskSia factors and cancels.
Scale a recipe for 4 to a recipe for 6. Each ingredient gets multiplied by 6/4 = 3/2.
