Find the product: two thirds multiplied by three fourths. Use the fraction model to help you. A rectangle partitioned into four equal parts, the fraction one fourth is above each part. Three parts are shaded, the fraction three fourths is above. The rectangle is then partitioned into three rows, the fraction one third is to the left of each row. Two rows are shaded, the fraction two thirds is to the left. The squares where the third column and two rows intersect are shaded darker.
