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.

Your welcome:)

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.

To find the sum of fractions with unlike denominators, you need to first find a common denominator. Here's how you can do that:

Step 1: Determine the least common multiple (LCM) of the denominators. In this case, the denominators are 8 and 2. The LCM of 8 and 2 is 8.

Step 2: Convert both fractions to have the same denominator. To convert 3/8 to have a denominator of 8, multiply both the numerator and denominator by 1, resulting in 3/8. To convert 1/2 to have a denominator of 8, multiply both the numerator and denominator by 4, resulting in 4/8.

Now that both fractions have a denominator of 8, you can add them together:

3/8 + 1/2 = 3/8 + 4/8

Step 3: Add the numerators and keep the common denominator unchanged.

3/8 + 4/8 = (3 + 4)/8 = 7/8

The sum of 3/8 and 1/2 when the denominators are made like is 7/8.
