Answer:
6.66 yards of ribbon.
Step-by-step explanation:
If she has 10 yards of ribbon and divides it equally into three parts, those 3 parts would each be 3.33 yards long or 3 (1/3) yards long. 
If she uses two of those parts on gifts, then she would use 3.33 x 2 or 6.66 yards of ribbon.

Find two numbers with a sum of 20 and a difference of 14
Make two equations 
X+Y=20
X-Y=14
Now add x since y cancels out and add 20+14 To end up with
2x=34
Now divide 2 both sides to get x alone 
2x/2=34/2
X=17
Now substitute x answer to first equation and solve for y 
17+y=20
Subtract 17 both sides
Y= 3
Your two numbers are 
3 and 17
