Answer 1

Step 1

A tape diagram is a rectangular drawing that appears like a tape piece with divisions to support mathematical calculations. It is a graphic tool used commonly in solving ratio-based mathematical word problems. Tape diagrams are visual representations that represent the sections of a ratio by using rectangles.

Step 2:

$\begin{gathered} 21\text{ }\frac{.}{.}\text{ }\frac{3}{8} \\ =\text{ 21 }\times\text{ }\frac{8}{3} \\ =\text{ 7 }\times\text{ 8} \\ =\text{ 56} \end{gathered}$
