1.)200,000 2.)400,000
3.)900,000
example:155,000 in the hundred thousanths place is a 1, so then u look at the number right beside it on the right side. and a rule when ur rounding is 5 or more raise the score, 4 or less let it rest. the number to the right of it is a 5,so u make the 1 go 1 number up.,which is 2, then u make all the numbers to the right a 0.so it would be 200,000 rounded to the nearest hundred thousanth
