Math Clip Art--Dividing Fractions by Whole Numbers--Example 129--Seven Eighths Divided by 4

Topic

Fraction Operations

Description

This math clip art image illustrates the process of dividing seven-eighths by 4 using a rectangular model. The model depicts a rectangle divided into eight equal horizontal strips, with seven of these strips shaded to represent seven-eighths. To demonstrate the division by 4, each horizontal strip is further divided into four equal parts using vertical lines, creating 32 total parts.

In this model, the original seven-eighths (7 horizontal strips) are now divided into 28 smaller rectangles. When we divide these 28 parts among 4 (the divisor), we get 7 small parts per group. These 7 small parts out of 32 total parts give us the final answer: 7/32.

This visual representation helps students understand that dividing a fraction by a whole number results in a smaller fraction. It also demonstrates how the denominator of the original fraction is multiplied by the divisor to get the new denominator (8 * 4 = 32).

Teacher's Script: "Observe our fraction model showing seven-eighths. We need to divide this into 4 equal parts. How can we do this? We'll divide each eighth into 4 smaller pieces using vertical lines. Count how many of these new, smaller rectangles are shaded. Now, let's divide these shaded parts into 4 groups. How many small parts are in each group? What fraction of the whole does this represent?"
