Round five thousand six hundred twenty-nine and three-tenths to the nearest hundred.

We want to take our number five thousand six hundred twenty-nine and three-tenths and round it to the nearest hundred. There is currently a six in the hundreds place. In order to round to the nearest hundred, we’ll need to look at the digit to the right of the hundred. We’ll need to look at the tens place.

If the digit in the tens place is greater than or equal to five, then we round up. If the digit in the tens place is less than or equal to four, then we round down. In this case, there is a two in the tens place. Two is less than four, so we need to round down.

When you round down, the digit you were rounding, in our case the six in the hundreds place, stays the same. Our six stays the same. The five in the thousands place also stays the same. And every digit to the right of the hundreds place becomes a zero.

When we’re rounding to the nearest hundreds place, we don’t need a decimal. We can say five thousand six hundred twenty-nine and three-tenths rounded to the nearest hundred equals 5600.
