Verified Answer :

We
need to rename the given number which is 780 000 into 78 ________.

=> But before we rename it, we need to find the value of 78

=> Since this is a 6 digit whole number, we have ones, tens, hundreds,
thousands, ten thousands, hundred thousands.

=> 7 = hundred thousands

=> 8 = ten thousands

=> 7 hundred thousands + 8 ten thousands

=> Thus, the renamed of 780 000 is 7 hundred 8 ten thousands.
