This video tutorial from Mumo Math and Science explains how to convert a decimal to a fraction, specifically focusing on converting 4/10. The process involves writing the decimal as a fraction over 1, multiplying both the numerator and denominator by 10 to eliminate the decimal, and then simplifying the fraction by finding the greatest common factor (GCF). A factor tree is used to determine the GCF, and the fraction is simplified to its lowest terms. The video concludes with a reminder to be kind.

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

• Multiply by 100

• Write the decimal over 1

• Subtract 1 from the decimal

• Add 10 to the decimal

How do you convert 4/10 to a whole number?

What is the greatest common factor of 4 and 10?

• 4

• 5

• 2

• 1

Which method is used to find the greatest common factor?

• Division

What is the simplified form of 4/10?

• 1/5

• 4/5

• 2/5

• 3/5

Why can't the fraction 2/5 be simplified further?

• The numbers are too large

• It is already in its simplest form

• It is already a whole number

• The numbers are not divisible by 2
