What is the resulting fraction when we add:
Give the answer in the simplest form.
Let's take the longer way of adding 3 and 2/5. By doing so, it will help us to understand adding fractions better. Since 3 is a whole number, we can change it into a fraction as shown:
We now have:
Now, since these fractions have unlike denominators, we can make the denominators the same by using Equivalent Fractions.
We can do so by multiplying the numerator and denominator of 3/1 with 5 as shown below:
With the denominators the same, we can now add these fractions together:
Notice that 17/5 is an improper fraction? Rather than leaving the answer like this, it is better to change it into a mixed fraction.
So, we have the answer as 3 2/5.
Now, with some observations, realize that we can quickly get the answer by just combining the whole number and the fraction together. This is shown below:
Clearly, the answer is C.
