Answer: see below
Explanation:
In order to compare these fractions, we must first ensure that the fractions have common denominators (that is the number under the fraction bar). The easiest way to do this is to find the smallest number that both are factors of, which in this case can be done by multiplying 3 by 5. This equals 15. Now, whatever we multiply by the denominator to get 15, we must also multiply by the numerator.
1/3 * 5/5 = 5/15
2/5 * 3/3 = 6/15
Now that the denominators are the same, we can compare the numerators to find the larger fraction. Since 5 is less than 6, 1/3 < 2/5. Hope this helps!
