Converting Decimals to Fractions

This video tutorial from Mumo Math and Science explains how to convert the decimal 0.75 into a fraction. It begins by multiplying the decimal by 100 to eliminate the decimal point, resulting in the fraction 75/100. The video then demonstrates how to simplify this fraction by finding the greatest common factor (GCF) using factor trees. The GCF is determined to be 25, and the fraction is simplified to 3/4. The tutorial concludes with a reminder to practice kindness.
