A general score is to divide several scores with different denominators into scores with the same mother but the same value. The same denominator after ten thousandths is called the common denominator, and usually the least common multiple of each fractional denominator is taken as the common denominator.

For example: 1/2 and 1/3.

The answer process is as follows:

1. Find the least common multiple of denominator 2 and denominator 3. The least common multiple of denominator 2 and denominator 3 is 6.

2. The denominator Hua Song is the least common multiple, and the numerator is multiplied by the denominator. 1/2=( 1×3)/(2×3), 1/3=( 1×2)/(3×2)。

3、 1/2=3/6, 1/3=2/6。 (The letters of two fractions are the same, so the general fractional solution is completed).
