如何计算Equivalent Fractions

learn.whatIsHeading

Equivalent fractions are different fractions that represent the same value. Multiplying or dividing both the numerator and denominator by the same non-zero number produces an equivalent fraction. Simplifying a fraction to its lowest terms means dividing by the GCD.

公式

To find missing numerator: use proportion — a/b = x/d → x = a×d/b
To
x/d → x = a×d/b — x/d → x = a×d/b
b
x/d → x = a×d/b — x/d → x = a×d/b
x
a×d/b — a×d/b

分步指南

  1. 1To create an equivalent fraction: multiply top and bottom by the same number
  2. 2To simplify: divide top and bottom by their GCD (Greatest Common Divisor)
  3. 3To find missing numerator: use proportion — a/b = x/d → x = a×d/b

例题解析

输入
2/3 equivalent to ?/12
结果
8/12
12/3 = 4, so 2×4 = 8. Check: 8/12 = 2/3 ✓
输入
Simplify 18/24
结果
3/4
GCD(18,24) = 6. 18÷6 = 3, 24÷6 = 4
