5th grade math homework help-rounding up?

Question

I'm a parent that has forgotten...ANYWAY,

1) To the nearest ten thousand:

9,468,354

2) To the nearest hundred million

301,426,999

3) To the nearest 10

834,290,776,359

This is just 3 of 12 questions, I need to know how to explain the rounding up to her.

Answer 1

To round something to the nearest place, you look at the place one to the right. If it's four or lower, you change that digit and all the others to the right of it to zero. If it's five or above, you change that digit and all the others to the right of it to zero, and raise the original place's digit by one. So #1 is 9,470,000, #2 is 300,000,000 and I can't see what you're asking for with #3.

Answer 2

1. 470,000

2. 300,000,000

3. 834,290,776,360

basically, you find the number, and if the number to the right of it is 5 or more, round the original number up, but if the number to the right is 4 or less, round the original number down.

example:

38 would round to 40

32 would round to 30

once you have done that, you should have all zeros to the right of the original number. for number 1, you had to round to the nearest ten thousand, so you round that, but the numbers to the left stay the same, like 4 stayed the same. for number 3, since you only had to round to the tenths, everything to the left of the 6 stays the same.

example:

round to nearest one hundreths:

starting number: 1,234,567

rounded to: 1,234,600  <----the numbers to the left of 6 stayed the same, and the numbers to the right became zeros.

Answer 3

When I was in the fifth grade, I had a hard time doing any kind of math, except for the simple 2+2=4.  

Answer 4

1)

9,468,354

The ten thousands digit is 6.

The 6 is rounded up because the thousands digit is 5 or above.

9,470,000

2)

301,426,999

The hundred millions digit is 3

The 3 remains the same because the ten millions digit is 4 or below.

300,000,000

3)

834,290,776,359

The tens digit is 5.

The tens digit is rounded up because the units digit is 5 or above.

Good luck explaining to your daughter.

Answer 5

If you, the parent, are having problems with 5th grade math (Are You Smarter Than A Fifth Grader?), you might want to learn to research.  From google, you can enter "grade school math rounding".  I found this site:  http://www.k111.k12.il.us/King/math.htm#...

This helps you, with your child, review the "how to" and not just ask for the answers.

This not only helps you learn, but teaches your child to research and learn.

Answer 6

1)  9,470,000.

2)  300,000,000.

3)  834,290,776,360.

a number that is 5 or above, gets rounded up.  a number less than 5 is rounded down.

the placement (tens, thousands, ten thousands, etc) is something you may want to study to refine where those placements are.

Answer 7

9, 468, 000

301,427,000

834, 291,000,000

Answer 8

you need to know the place values....from right to left to right thousandths, hundredths, tenths, ones, tens, hundreds, thousands, ten thousands, hundred thousands, millions, ten millions, hundred millions, billions, ten billions, hundred billions....and so on and on and on to infinity

if the number in the place before the place you are rounding to is 5 or larger you round up, if it is four or lower you round down

example 1 to the nearest ten thousand:9,468,354 = 9,470,000.....hope that helps

Answer 9

1) 9,468,354 To the nearest 10,000 is

9,470,000

If the number before the tenthousand place is above or = to 5 round up

next is the same idea

300,000,000

If the number before of the 100 million spot is over 5 or = to 5 round up

and the last is 834,290,776,360

Answer 10

for number one its is the 6 after the nine and u see the 8  to if the 8 is higher then a 5 the six turn sinto a 7
