15,000 --> fifteen thousand
400 --> four hundred
00 --> zero
9 --> nine
If you put this all together it gives you fifteen thousand four hundred and nine.
multiply the height x the length x the width to find the volume of a room (or another 3d object)
1 quarter = 25 cents (he has 2 therefore its 50 cents)
10 dimes = 100 cents = 1 dollar
Oliver has twice as many dimes than he does quarters because 100 divided by 50 = 2. Hope this helps!
