Answer: 11/4, 17/15
Step-by-step explanation:
1. To evaluate this, you are going to need the denominator to be the same for both fractions in the equation. Start with finding the least common denominator.
5/4 and 3/2 have the least common denominator of 4, so you can multiple 3/2 by 2/2 to get 6/4. This doesn't change the value of the fraction.
Now we have 5/4+6/4= 11/4
Simplify and the answer 2 and 3/4.
2. Find the least common denominator.
9/5-2/3=__
LCD= 15
Expand the fractions so they both have the same denominator.
27/15 - 10/15 = 17/15
Simplify.
1 and 2/15
