You just have to...
fiddle...
around with the graph.
And try to figure out things.
I spent 20 minutes on this.
and couldn't get quite close to a cross.
sorry.
2/5 is equivalent to 4/10 so at the end of February 4/10 was used up
And at the end of January, 3/10 was used
so 4/10 + 3/10 = 7/10
At the end of February, 7/10 of the wood was used
The boxes from left to right are
100
2
25/3
The ratio is 5/3 pies to cakes so
Top square = bottom square times 5/3
OR
Bottom square = top square times 3/5
