Step-by-step guide on adding fractions with unlike denominators using LCM and visual models.
A hand-drawn educational diagram illustrating how to add fractions with unlike denominators, showing the process of finding the least common multiple (LCM) of 4 and 3 to convert 1/4 and 1/3 into 3/12 and 4/12, then adding them to get 7/12, with visual representations using grids and bars.
