To convert the mixed number 12 5 into a fraction, we first need to understand its components. The number 12 is the whole number, and the number 5 is the numerator of the fractional part. The denominator is usually assumed to be 1 unless otherwise specified.
Here are the steps to convert it:
- Multiply the whole number (12) by the denominator of the fraction (1, in this case): 12 × 1 = 12.
- Add the result to the numerator (5): 12 + 5 = 17.
- Place the sum over the original denominator (1): 17/1.
However, we can also express this mixed number as an improper fraction. Since there isn’t an explicit denominator given for the 5, we can express the whole number part as a fraction too:
The whole number 12 can be written with a denominator that we choose for the fractional part, for example, if we treat the 5 as having a denominator of 1 then:
12 = 12/1
Now we can rewrite 12 5 as:
12 5 = 12 + 5 = 12/1 + 5/1 = (12 + 5)/1 = 17/1.
This means that 12 5 as a fraction is simply 17.
