What is five sixths plus five sixths?

Answer 1

A fraction is composed of a numerator (top number) and a denominator (bottom number). When adding fractions whose bottom numbers are the same, just add the top numbers and leave the bottom.

5/6 + 5/6 = 10/6. Done. But you can simplify that to 5/3...which is the same number, just expressed differently.

A more difficult example would be: 3/4 + 5/6. Well now the denominator is different each time...what do we do? Find a number both will go into perfectly.

So what do 4 and 6 go into? The easier number is 12.

4x3 = 12 and 6x2 = 12

So we know to times the 3/4 by 3 (both top and bottom) and the 6x2 by 2

= 9/12 + 10/12. They still the same numbers...it's the same amounts, just expressed differently. But we've made the denominators the same.

Now we add them

= 19/12. Cannot be simplified as 19 is a Prime number, so this would be the answer.

Answer 2

10/6
