Round to the nearest ten and hundreds.
Let's solve this ------
To round to the nearest tens, you need to know what number is sitting in the tens place. 6 is the number that is sitting in the tens. You need to also make sure whether the number next to 6 is greater or lesser than 5. If its lesser, you need to add a zero. If its greater, you need to add plus 1 to the tens place.
363 rounded to nearest tens is -- 360.
Its the same case for the hundreds place.
363 rounded to the nearest hundreds is ---- 400.
Hope I helped.
