Yes, you need to make the denominators the same. 2/3 becomes 8/12. So now you add 7/12 and 8/12, getting 15/12. But you're not done you need to simplify 15/12. The answer is 1 1/4.
Answer:
.2
Step-by-step explanation:
(.35((.05)).25)
.05/.25 = .2
#1)
-5-3=-8
-2x=-8
x=4
#2
D.) 5-2=3
#3
D.) 5×-2=-10
4x-2(3)=2y
4x-6=24
12-2(-6)=24
y=-6
12+12=24
