Question

hey tbis is my last home work question been on it for like 12 minutes could some one give me the answer but explain how they got it 9/14 + (- 3/4)

Answer 1

adding a negative number is the same thing as subtracting so



to add/subtract fractions, you need a common denominator

Find a common denominator by finding a common multiple of 14 and 4. Basically, if you add 4 + 4 +4 +4 +4 and on, when is that number the same as one of the 14 + 14 + 14 ones
