Converting Recurring Decimals to Fractions

This video tutorial explains how to convert recurring decimals into fractions. It begins by defining recurring decimals and their notation. The video then provides a detailed, step-by-step guide on converting these decimals into fractions, including cases where the recurring part does not immediately follow the decimal point. The tutorial concludes with encouragement to practice the techniques discussed.

What is a recurring decimal?

• A decimal that is always less than 1

• A decimal with no repeating pattern

• A decimal where digits repeat indefinitely

• A decimal that terminates after a few digits

How do we represent a recurring decimal like 0.473473...?

• 0.473 with a bar over 473

• 0.473 with dots above 4 and 3

• 0.473 with a bar over 4 and 3

• 0.473 with a dot above 7

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

• Multiply the decimal by 100

• Name the decimal with a letter

• Subtract the decimal from 1

• Divide the decimal by 10

Why do we multiply the decimal by 10 repeatedly?

• To get rid of the decimal point

• To make the decimal larger

• To get a full set of recurring digits to the left of the decimal point

• To simplify the decimal

What do we do after obtaining a full set of recurring digits to the left of the decimal point?

• Divide by the number of recurring digits

• Multiply by 10 again

• Add the decimal to itself

• Subtract the original decimal from the new value

In the example of converting 0.473 recurring, what is the final fraction obtained?

• 473/999

• 47/100

• 473/1000

• 47/999

How do we handle a recurring decimal where the recurring part does not start immediately after the decimal point?

• Divide by the number of non-recurring digits

• Multiply by 100 directly

• Subtract the decimal from 1

• Use two extra sums

What is the main aim when subtracting one equation from another in this process?

• To get a larger number

• To simplify the equation

• To remove the recurring decimal part

• To get a smaller number

In the example of converting 0.23 recurring, what is the simplified fraction obtained?

• 7/30

• 21/90

• 23/100

• 2/3

What should you do if you find the topic of converting recurring decimals to fractions confusing?
