To convert the fraction 9/20 into a decimal, follow these simple steps:
- Understand the fraction: The fraction 9/20 means 9 divided by 20.
- Perform the division: You can do this division with a calculator, or manually. Dividing 9 by 20, you can set it up as follows:
9 ÷ 20
- Long division method: If you do it manually, you notice that 20 goes into 9 zero times (0). So you write down 0, add a decimal point, and a zero to make it 90.
- 20 goes into 90 four times (4), since 20 x 4 = 80. Write down 4.
- Subtract 80 from 90, which leaves you with 10. Bring down another zero, making it 100.
- Now 20 goes into 100 exactly five times (5), since 20 x 5 = 100. Write down 5.
- Subtract 100 from 100, which equals 0. Since there’s nothing left, you can stop here.
So, after performing the division, we get:
9/20 = 0.45
Therefore, the decimal equivalent of 9/20 is 0.45.
