5-34.

Complete the diagram below and write the multiplication problem and answer that would go with it.

 Generic rectangle top edge left$4$ top edge right$+\frac{1}{5}$ left edge top blank interior top left$12$ interior top right blank left edge bottom$+\frac{2}{3}$ interior bottom left blank interior bottom right blank

Divide 12 by 4 to find the missing dimension of the rectangle.

$\frac{12}{4}=3$

Then find the other dimensions using multiplication.

$12+\frac{3}{5}+\frac{8}{3}+\frac{2}{15}$
