Rounding Mixed Numbers and Fractions

In this video, Mr. J explains how to round mixed numbers to the nearest whole number using four examples. The key concept is to examine the fractional part of the mixed number: if it is greater than or equal to half, round up; if less, stay the same. The video covers examples with different fractional parts, demonstrating the rounding process and emphasizing the importance of understanding the fractional part's value relative to half. The video concludes with a recap of the rounding strategy.
