The sum is approximately $\square$

Studdy Solution

STEP 1

What is this asking? We need to round two big numbers to the nearest hundred thousand and then add them together. Watch out! Don't round to the nearest ten thousand or million!
We're focusing on the hundred thousands place.

STEP 2

1. Round the first number.
2. Round the second number.
3. Add the rounded numbers.

STEP 3

Let's look at our first magnificent number, $983,123$ .
We want to round it to the nearest hundred thousand.
The hundred thousands place is the $9$ .

STEP 4

To the right of the hundred thousands place is the ten thousands place, which has an $8$ .
Since $8$ is greater than or equal to $5$ , we round up the hundred thousands digit.

STEP 5

Rounding up the $9$ in the hundred thousands place bumps it up to $10$ , which carries over to the millions place, giving us $1,000,000$ !
So, $983,123$ rounded to the nearest hundred thousand is $1,000,000$ .

STEP 6

Now, let's work our magic on the second number, $989,514$ .
We're still rounding to the nearest hundred thousand, so we look at the hundred thousands place, which is a $9$ .

STEP 7

Looking to the right, we see an $8$ in the ten thousands place.
Since $8$ is greater than or equal to $5$ , we round up again!

STEP 8

Rounding up the $9$ in the hundred thousands place gives us $10$ , which carries over to the millions place.
So, $989,514$ rounded to the nearest hundred thousand is also $1,000,000$ .

STEP 9

Time to add our rounded numbers!
We have $1,000,000$ and $1,000,000$ .

STEP 10

$1,000,000 + 1,000,000 = 2,000,000$

STEP 11

The sum is approximately $2,000,000$ .

1. Round the first number.2. Round the second number.3. Add the rounded numbers.

STEP 3

Let's look at our first magnificent number, 983,123983,123983,123.We want to round it to the nearest hundred thousand.The hundred thousands place is the 999.

STEP 4

To the right of the hundred thousands place is the ten thousands place, which has an 888.Since 888 is greater than or equal to 555, we **round up** the hundred thousands digit.

STEP 5

Rounding up the 999 in the hundred thousands place bumps it up to 101010, which carries over to the millions place, giving us 1,000,0001,000,0001,000,000!So, 983,123983,123983,123 rounded to the nearest hundred thousand is **1,000,0001,000,0001,000,000**.

STEP 6

Now, let's work our magic on the second number, 989,514989,514989,514.We're still rounding to the nearest hundred thousand, so we look at the hundred thousands place, which is a 999.

STEP 7

Looking to the right, we see an 888 in the ten thousands place.Since 888 is greater than or equal to 555, we **round up** again!

STEP 8

Rounding up the 999 in the hundred thousands place gives us 101010, which carries over to the millions place.So, 989,514989,514989,514 rounded to the nearest hundred thousand is also **1,000,0001,000,0001,000,000**.

STEP 9
