What is four fifths plus one third making the denominator the same?

Answer 1

seventeen over fifteen

because the common denominator of 5 and 3 is 15

think about it like this:

4/5x3, 4x3=12, 5x3=15

1/3x5, 1x5=5, 3x5=15

so you get 12/15+5/15 see how they simplify back?

then add the numerators and keep the denominator and you get 17/15 or 1 and 2/15
