We can represent multiplication using diagrams.

\(\Large 4\times 6\)

\(\Large 3\times \dfrac{1}{4}\)

\(\Large 6 \times 0.5\)

E.g., \(4\) tables with \(6\) people at each.

E.g., \(3\) pieces of one-quarter of a pizza.

E.g., \(6\) laps of a \(0.5\) km race track.

Solution

\(\Large 6+6+6+6 \class{timed add2-cover remove3-cover}{= 4 \times 6} \class{timed add2-cover remove4-cover}{ = 24}\)

We use multiplication to represent the repeated addition.  

Thus, \(24\) students can attend the class lunch.
