First, we will find the sum of the fractions:
Now we get the exercise:
\( 13+5+5= \) ?
The denominator tells you what size pieces you're working with. Since both fractions use sevenths, you're adding pieces of the same size. Adding denominators would change the piece size, which doesn't make sense!
When the numerator and denominator are equal, the fraction equals 1 whole unit. Think of it as 7 pieces out of 7 total pieces - that's the complete whole!
You can, but it's usually easier to add the fractions first. This way you can see if they make a whole number, then combine everything at the end.
No problem! Just add the whole number to whatever fraction you get. For example: (a mixed number).
Not in this problem! Both fractions already have the same denominator (7). You only need to find a common denominator when the denominators are different.
