Molly has 9 cups of flour. If this is 3/4 of the number she needs to make bread, how many cups does she need?a. Construct the tape diagram by reading it backward. Draw a tape diagram and label the unknown.b. Next, shade in 3/4.c. Label the shaded region to show that 9 is equal to 3/4 of the total.d. Analyze the model to determine the quotient.

Answer:a. In constructing the tape diagram,Take a grid that shows the total number of cups of flour required to make bread,b. Shade 3/4th of the total grid,c. According to the question,[tex]\frac{3}{4}[/tex] part of the grid = 9Mention it on the model,d. By cross multiplication,[tex]\implies 1 \text{ part } = 9\times \frac{4}{3}=3\times 4=12[/tex]Hence, the whole part of the grid would be 12.That is, 12 cups are needed to make the bread.
