Measuring Insects (Represent decimals using the number line and equivalent fractions)

The video tutorial explains how to measure insect lengths and convert them from fractions to decimals using a number line. It covers the representation of tenths and hundredths, using examples of a worm, centipede, and ladybug. The tutorial demonstrates how to divide a number line into equal parts to represent fractions as decimals, providing a clear understanding of decimal conversion.

What is the first step in converting a fraction to a decimal using a number line?

• Divide the number line into equal parts based on the denominator.

• Subtract the numerator from the denominator.

• Multiply the numerator by 10.

• Add the numerator and denominator.
