Rename the number 4 thousand 7 hundreds = 47

47 hundred

Explanation:
First we will translate the wordings into numbers:
4 thousands = 4 * 1000 = 4000
7 hundreds = 7 * 100 = 700

Therefore:
4 thousand 7 hundreds = 4000 + 700 = 4700

Now, we have a portion of 47 taken out, we will get the remainder as follows:
 = 100 which is written as "hundred"

Based on the above, we can rename 4 thousands 7 hundred into 47 hundred

Hope this helps :)
