I think you mean how many thousands equal 20 hundreds. Well it's simple, 20 hundreds equal 20*100 which equals 2,000. Therefore, 20 hundreds equals 2 thousands.
We know that
Jayden cleans 12 rooms in---------------> <span>6 hours
X rooms-------------------------------------> 4 hours

that means </span>Jayden cleans in 4 hours 8 rooms
Chandra cleans 12 rooms in---------------> 12 hours
X rooms-------------------------------------> 4 hours
X=4*12/12--------> 48/12---------> 4 rooms
that means Chandra cleans in 4 hours 4 rooms
the answer is
<span>Jayden = 8 blankrooms
</span><span>Chandra = 4 blankrooms</span>
