4/5-(-2/3)=?

1 Answer

#22/15 = 1 7/15#

Explanation:

#4/5 + 2/3# .

This is the expression because when you have 2 negatives they make a positive. Then it becomes a normal addition of fractions and you have to find a common denominator which is #15#.

So therefore whatever you do to the denominator(the bottom) you must do to the top.

So #(4 * 3) / 15 + (2*5) /15 #

which equals #12/15 + 10 /15.#

This makes #22/15#.
