Converting a decimal to a fraction is a simple process that can be done in a few easy steps. Here's how to convert 2.2 to a fraction:
Step 1: Identify the Decimal Part
The decimal part of the number is 0.2. To convert this to a fraction, we need to determine the place value of the last digit. In this case, the last digit is 2, which is in the tenths place.
Step 2: Convert the Decimal to a Fraction
To convert the decimal to a fraction, we can divide the decimal part by the place value of the last digit. In this case, we divide 0.2 by 10 (since it's in the tenths place).
0.2 ÷ 10 = 2/10
Step 3: Simplify the Fraction (Optional)
The fraction 2/10 can be simplified by dividing both the numerator and denominator by 2.
2 ÷ 2 = 1 10 ÷ 2 = 5
So, the simplified fraction is:
1/5
Therefore, 2.2 as a fraction is:
2 1/5
Or, if you want to keep it as a single fraction:
11/5
And that's it! With these easy steps, you can convert any decimal to a fraction.
