  • Question 12 (request help)

    Jill is making a long cape. She needs \(4\frac{1}{3}\) yards of blue fabric for the outside of the cape. She needs \(3\frac{2}{3}\) yards of purple fabric for the lining of the cape.

    Part A

    Jill incorrectly subtracted the two mixed numbers to find how much more blue fabric than purple fabric she should buy. Her work is shown below.

    \(4\frac{1}{3}-3\frac{2}{3}=\frac{12}{3}-\frac{9}{3}=\frac{3}{3}\)

    Why is Jill’s work incorrect?
