Example 1: Round 7. 86 to the nearest tenth. Example 2: Round 247. 137 to the nearest tenth.
Example 1: In the number 7. 86, the 8 is in the tenths place. Example 2: In the number 247. 137, the 1 is in the tenths place.
Example 1: In the number 7. 86, the 6 is in the hundredths place. Example 2: In the number 247. 137, the 3 is in the hundredths place. The digits to the right of the hundredths do not matter when you’re rounding to the nearest tenth. They represent “extra stuff” too small to make a difference.
Example 1: The number 7. 86 has a 6 in the hundredths place. Round up by adding 1 to the tenths place to get 7. 9, removing the digits to the right.
Example 2: The number 247. 137 has a 3 in the hundredths place. Round down by removing everything past the tenths place, to get 247. 1.
Be careful about using the phrases “round down” and “round up. " If you look at a number line for negative numbers, you’ll see that rounding -12. 56 to -12. 6 moves left, so that’s “rounding down” even though you increased the tenth digit by 1.
