How do you get the answer for addition with unlike denominators:
3/8 + 1/2=
You must make the denominators the same by multiplying the numerator and the denominator of 1/2 by four to get 4/8.
Answer is wrong can someone else help?
Her answer was right, she just didn't complete the problem for you. 1/2=4/8 so you now have 3/8+4/8=7/8.
