ELEN [110]

Missing part of question:

Draw a tape diagram to show how much cake each of the five children received.

Answer:

See attachment

Step-by-step explanation:

Equal\ Pieces = 6

Children = 5

Required

Tape diagram to represent the scenario

Because one child is not hungry, the number of children to share the cake becomes 6.

So, first we calculate the share of each child.

Share = \frac{Pieces}{Children}

Share = \frac{6}{5}

Share = 1.2

See attachment for tape diagram

The tape diagram implies that:

5 * 1.2 = 6

or

\frac{6}{1.2} = 5

or

\frac{6}{5} = 1.2
