Change these fractions to equivalent fractions with a common denominator. Add the numerators.

I'll be glad to check your answer.

oh.. I got 23/40. Is that right?

Yes, that's correct.

To find out what fraction of her assignment Mara completed on Saturday and Sunday, we need to add the fractions for each day together.

On Saturday, Mara completed 1/5 of her assignment.
On Sunday, Mara completed 3/8 of her assignment.

To add these fractions, we need to find a common denominator. The least common multiple (LCM) of 5 and 8 is 40.

Now, let's convert the fractions so that they have the same denominator of 40:

1/5 = (1/5) * (8/8) = 8/40
3/8 = (3/8) * (5/5) = 15/40

Now that the fractions have the same denominator, we can add them together:

8/40 + 15/40 = 23/40

Therefore, Mara completed 23/40 of her assignment on Saturday and Sunday.
