The garden club
plans its spring and
summer garden.
They have 20 plots.
In 3 plots they will
sow tomatoes, in 5
plots they will sow
cabbages, in 6 plots
they will sow
strawberries, in 2
they will sow
courgettes and in 4
plots they will sow
melons.

Make a percentage bar graph of the relative frequencies of the plots in the garden.

Can someone tell me up to where I mark them on the bar graph?
