1.4 as a mixed number
Understand the Problem
The question is asking how to convert the decimal 1.4 into a mixed number format, which consists of a whole number and a proper fraction. To do this, we will separate the whole number from the decimal part and convert the decimal part into a fraction.
Answer
\( 1 \frac{2}{5} \)
Answer for screen readers
The final answer is ( 1 \frac{2}{5} ).
Steps to Solve
- Separate the whole number and decimal part
The whole number part of 1.4 is 1, and the decimal part is 0.4.
- Convert the decimal part to a fraction
To convert 0.4 into a fraction, we know that 0.4 can be written as $\frac{4}{10}$.
- Simplify the fraction
Next, we simplify $\frac{4}{10}$. We can divide both the numerator and the denominator by their greatest common divisor, which is 2:
$$ \frac{4 \div 2}{10 \div 2} = \frac{2}{5} $$
- Combine the whole number and the simplified fraction
Now, we can write 1.4 as a mixed number. Combine the whole number and the fraction:
$$ 1.4 = 1 \frac{2}{5} $$
The final answer is ( 1 \frac{2}{5} ).
More Information
Converting decimals to mixed numbers is a useful skill, especially in fractions and measurements. Mixed numbers make it easier to understand quantities in a clear whole and fractional format.
Tips
- Forgetting to simplify the fraction: Always check if the fraction can be simplified.
- Misidentifying the whole number: Ensure you correctly separate the decimal from the whole number part.
