Answer for screen readers
The mixed number form of 3.2 is ( 3 \frac{1}{5} ).
Steps to Solve
- Identify the whole number part
The whole number part of the decimal 3.2 is 3.
- Identify the fractional part
To find the proper fraction, we look at the decimal part, which is 0.2.
- Convert the decimal to a fraction
We can express 0.2 as a fraction. Since it is in the tenths place, we can write it as:
$$ 0.2 = \frac{2}{10} $$
- Simplify the fraction
The fraction can be simplified by dividing the numerator and denominator by their greatest common divisor (GCD), which is 2:
$$ \frac{2}{10} = \frac{1}{5} $$
- Combine the whole number and the fraction
Finally, we combine the whole number and the simplified fraction to form a mixed number:
$$ 3.2 = 3 \frac{1}{5} $$
The mixed number form of 3.2 is ( 3 \frac{1}{5} ).
