Rounding Decimals and Whole Numbers

The video tutorial explains how to round decimals with one decimal place to the nearest whole number. It begins by identifying the whole numbers before and after the decimal, then finds the halfway point between them. Using a number line, the tutorial demonstrates how to locate the decimal and determine which whole number it rounds to. An abstract method is also introduced, focusing on circling and underlining digits to decide whether to round up or down.
