The fraction models below represent two fractions of the same whole. How much of the Fraction 3 over 8 is in the Fraction 1 over 4? Two rectangles of the same size are drawn side by side touching each other. The first rectangle is divided into 8 portions of equal size. Three of these are shaded. The shaded portion alone is labeled as 3 over 8. The second rectangle is divided into 4 portions of equal size. One portion is shaded. The shaded portion alone is labeled 1 over 4. Fraction 1 over 4 Fraction 1 over 3 Fraction 2 over 3 Fraction 3 over 4
