## Converting Recurring Decimals to Rational Numbers Worksheet with Answers

**Example 1.
**Write the decimal 0.825 as a rational number?

**Solution:**

Given Decimal Number is 0.825

To write 825 thousandths we use place 825 over 1000

= 825/1000

Simplifying the fraction further we have 33/40

**Example 2.
**Convert 2.333… into a rational number?

**Solution:**

Given Recurring Decimal is 2.333…..

Place the repeating digit on the left side of the decimal point. To do so move it by multiplying the original number by 10.

10x = 23.333…..

x= 2.333……

10x-x =23.333….-2.333….

9x=21

x=21/9

Therefore, recurring decimal to a rational number is 21/9

**Example 3.
**Convert 10.3454545… into a rational number?

**Solution:**

Given Recurring Decimal x= 10.3454545……..

Place the repeating digit on the left side of the decimal point. To do so move it by multiplying the original number by 1000.

1000x = 10345.454545…..

Shift the repeating digits to the right side of the decimal point. Simply multiply with 10

10x= 103.4545……

1000x-10x =10345.454545…..- 103.4545……

990x=10242

x=10242/990

x=569/55

Therefore, recurring decimal to a rational number is 569/55

**Example 4.
**Convert the following repeating decimal 0.272727 as a rational number?

**Solution:**

Given Repeating Decimal x = 0.272727…..

Place the repeating decimal on the left side of the decimal point. Simply multiply the original number by 100

100x = 27.2727….

x = 0.272727……

Subtracting both the equations we have

100x-x=27.272727…….-0.272727…..

99x=27

x =27/99

**Example 5.
**Convert the following repeating decimal as fraction 0.37777

**Solution:**

Given repeating decimal = 0.37777…….

Place the repeating digit on the left side of the decimal point. To do so multiply the original number by 10

10x = 3.77777…..

x = 0.37777….

10x-x = 3.777….-0.37777….

9x =3.4

x=3.4/9

x=34/90

x=17/45

**Example 6.
**Convert 124.45757… into the rational fraction?

**Solution:**

Given Repeating Decimal x = 124.45757….

Move the repeating digit to the left side of the decimal point at first. To do so multiply with 1000

1000x = 124457.575…..

Now we need to transfer the repeating digits of decimal numbers to the right side of the decimal point. Simply multiply with 10

10x =1244.5757……

Subtracting both the equations we have

1000x-10x = 124457.575….. – 1244.5757……

990x= 123213

x=123213/990

x=41071/330

Therefore, recurring decimal 124.45757… converted to a rational number is 41071/330
