Question

Write four numbers that round to 700,000 when rounded to the nearest hundred thousand

Answer 1

Answer:

The four numbers can be 699,999, 699,998, 699,997 and 699,996.

Step-by-step explanation:

Consider the provided number 700,000

According to place value.

Hundred Th.    Ten Th.     Thousands   hundreds   Tens   Ones

 100,000            10,000       1000             100            10        1

We need write four numbers that round to 700,000 when rounded to the nearest hundred thousand.

The rule of rounding a number is:

If 0, 1, 2, 3, or 4 follow the number, then no need to change the rounding digit.

If 5, 6, 7, 8, or 9 follow the number, then rounding digit rounds up by one number.

To find the number when rounded to the nearest hundred thousand gives 700,000 simply subtract 1, 2, 3, and 4 from the provided number.

Let us subtract 1 from 700,000 that will gives us:

700,000-1=699,999

700,000-2=699,998

700,000-3=699,997

700,000-4=699,996

If we round the above four number to the nearest hundred thousand it gives 700,000. because the number at the ten thousand place is 9, so to round up the number increase the digit of hundred thousand place by 1.

The digit at the hundred place is 6 so increase it by 1.  i.e 7

Rounding up will gives us 700,000.

Thus, the four numbers can be 699,999, 699,998, 699,997 and 699,996.
