Question

Shirley is painting a rectangular tray. She paints part of the tray yellow and paints blue stripes on part of the tray. The fraction model below represents the whole tray and Shirley uses it to determine how much of the tray she paints yellow with blue stripes.

Using this fraction model, complete and solve the equation below to show how much of the tray she paints yellow with blue stripes.

Answer 1

1. First use the diagram to complete the equation.
2. There are 12 yellow squares shaded a/5=12/15=4/5, five blue squares shaded 1/b=5/15=1/3, and 15 squares in total 4/c=4/15.
3. Replace the letters with the corresponding numbers. 4/5 x 1/3 = 4/15
