Question

How do I add and subtract fractions with unlike denominators?

Answer 1

you change the denominators

Answer 2

I'll write up a example.

Answer 3

least common multiple you change the denominators so they are equil when you do this you also must change the numerator however

EX
1/2-1/3 the least common multiple is 6 so it becomes 3/6-2/6

Answer 4

by making the denominators equal by multiplying

Answer 5

2/8 Could be divided into 2. Making it 1/4.

Answer 6

So the answer to my example would be 2/4.

Answer 7

NO U DONT HAVE TO MULTIPLY THAT CAN MAKE IT A LOT HARDER THAN IT NEEDS TO BE
for example if you have 5/6 + 3/12
you can just multiply both the numerator and denominator of 5/6 by 2 and you get 10/12+3/12

Answer 8

Hinkey, that IS multiplying...
