# How To Round To The Hundredth

Learning when to round up or down is one of the first steps in basic math. Rounding to the hundredth can be tricky for beginners. People often confuse the "hundredth" position with the "hundreds" position. The primary difference is the side of the decimal on which the number is placed. You will find the "hundredth" position as part of the decimal (to the right of the decimal point); you will find the "hundreds" position as part of the whole-number (to the left of the decimal point).

### Step 1

Locate the hundredths position in your number. The hundredths position is the second number behind the decimal point.

### Step 2

Locate the thousandths position in your number. The thousandths position is the third number behind the decimal point.

### Step 3

Determine whether you need to round up or down. The value of the number in the thousandths position will determine whether you need to round up or down.

If the number in the thousandths position is "5" or above, you'll round up. If the number in the thousandths position is "4" or below, you'll round down.

### Step 4

Round the number in the hundredths position according to the number in the thousandths position.

Example:

100.235=100.24 or 100.234=100.23

### TL;DR (Too Long; Didn't Read)

Memorize the following prompt to help you determine when to round up or down: When the following number is five or more, round it high. When the following is four or below, round it low.
