ok. Proportional fractions are fractions that represent the same amount. The only way that could happen is by having the numerator and denominator proportional. For example: 1/2 is the same as 2/4. A relationship can be seen here; the numerator of
"1/2" was multiplied by 2, and so was the denominator. That means that fractions are only proportional if they are multiplied or divided by the SAME NUMBER. in this case, we have 2/5. if we multiply both the numerator and denominator by two we would get 4/10 (which is one proportional fraction). However, if we multiply the numerator and the denominator by 3 we would get 2x3=6 for the numerator and 5x3= 15 for the denominator. Therefore, the new fraction is 6/15, meaning that yes, these two fractions are proportional

Yes it is. And here's how you find out.
Proportional fractions are fractions that are equal to each other. An easy way to find out if these fractions are proportional is to just reduce the fraction 6/15 (since you can't reduce 2/5). Dividing 6 and 15 by their highest common factor, three, we get 2/5. So, therefore, 2/5=6/15. The fractions are proportional.
Although, you should only use this procedure in this type of problem. When it's just asking if the fractions are proportional. In other problems, just use this as a checking method.
There you go. I'm glad I could help. :)

2/5 = 6/15
6/15
Common factor of 6 and 15 is 3
3 divided into 6 = 2
3 divided into 15 = 5
2/5 = 2/5
2/5 is proportioal to 6/15
