Julius spent 1/10 of his weekly allowance on a set of markers and 2/5 of it on a book. what fraction of julios allowance is this altogether

Hi there!

What we have to do here is convert 2/5 so it has the same denominator as 1/10. To get the denominator to 10, we multiply 5 by 2, so we have to do the same to the numerator. So, 2/5 = 4/10.

Then, we add 4/10 + 1/10, which gives us 5/10.

This simplifies to 1/2.

I hope I helped!
