Now for the explanation, so you can do it yourself next time.
The amount you start with at each stage of the sum always, always, always represents 100%
100% maps on to $150,000
so 10% maps on to $ 150,000 x 10%/100%
=$150,000 x 10/100
= $15,000
Now I am inventing an extra step, so you can see how it works for more complicated sums.
Grand dad has offered to lend them 30% of the deposit they need. How much is he going to lend them?
This time it's the deposit that represents 100% and you and I are going to work out what 30% of it is.
100% maps on to $15,000
so 30% maps on to $15,000 x 30%/100%
30% maps on to $15,000 x 30/100
= $450,000 / 100
= $4500
So Grand dad will lend them $4500.
I included this extra bit to remind you that at each stage of the sum, the amount you start with represents 100%
Good luck

Basic math skills -- if you need help doing this math problem you need to speak with your teacher and get assigned extra tutoring help.
