- The shape below has some triangles shaded.
Shade some extra triangles so that `1/3` of the the shape is shaded. (1 mark)
- Using the shape in (a.) above, or otherwise, write two more fractions that are equivalent to `1/3`. (2 marks)

a. `5\ text(additional triangles need to be shaded (8 in total))`
`text(One possible solution.`
b. `8/24 = 4/12 = 2/6 = 1/3`
`text(Note: Many other fractions equivalent to)\ 1/3\ text(are possible.)`
Show Worked Solution
a. `text(There are 24 triangles altogether.)`
`text(Number of triangles)\ = 1/3 xx 24 = 8`
`:.\ 5\ text(additional triangles need to be shaded (8 in total))`
`text(One possible solution.`
b. `text(Using diagram)`
`8/24 = 4/12 = 2/6 = 1/3`
`text(Note: Many other fractions equivalent to)\ 1/3\ text(are possible.)`
