Math 115 15 & 16
posted by Deb .
#1. 1015/(3)(6)12
#2. 1115/(6)(4)18
this is what i come up with
#1 4/2418=4/6
#2 5/1812=5/6

From you notation, it is not clear whether the denominator is just the first of the two terms or both of them. I will first assume it is just the first number.
[1015/(3)] (6) 12 = (5/3)(6)  12 = 10  12 = 22
Now if it is both numbers.
[1015/(3)(6)] 12 = 5/18  12 =  5/18 216/18 = 221/18
Decide on your denominator and go through the same processes for the second problem.
I hope this helps. Thanks for asking.
