it read
Jill is three quaters the age of Keith. Jill is 9, how old is Keith?

I dont know if this is the best way of explaining, but I would tell my daughter to do this :

three quarters is 9.
this means one quarter is 3.
When you know, quarter is 3, the whole (or Keith'sage in this case ) must be 4 times 3 and hence the answer must be 12.

Hope this helps !!

thanks abr, this is what i thought, but wasn't sure if it's the corect way of explaining it.

many thanks for your reasurence.
still be interested if anyone has another view.
