Answer:
a) 15/8 b) 25/18
Step-by-step explanation:
a) First bring all the fractions to a common denominator (I'm going to use 8th's). 5/8 is already simplified, 1/2=4/8, and 3/4=6/8. Then, simply add the numerators and leave the denominator: ![\frac{5+4+6}{8} =\frac{15}{8}](https://tex.z-dn.net/?f=%5Cfrac%7B5%2B4%2B6%7D%7B8%7D%20%3D%5Cfrac%7B15%7D%7B8%7D)
Since this can not be simplified any further, your final answer is 15/8.
b) Start by bringing all the fractions to a common denominator (for this problem, we'll use 18th's). 2/3=12/18, 1/6=3/18, and 5/9=10/18. Then just add all the numerators and leave the denominator the same:
Since this cannot be simplified further either, your final answer is 25/18.
Hope this helps! :)
