P4 Maths ~ 2011 Mar 02, 1804hrs ~ Mum bought some grapes

I've got another maths question from a colleague with a Primary 4 child.

Question: 
Mum bought some grapes.
She ate 1/10kg, gave away 2/10kg and had 4/10kg left.
How much grapes did she buy?

Here's how I got the answer...

...just need to clarify on the model drawing:

How do I draw the model?
