Half of Sarah's wire is equal to 2/5 of Daniels. Chris has 3 times as much as Sarah. In all, their wire measures 6 ft. How long is Sarah's wire in feet?

1. Dan ---- x
Sarah ---(2/5)x
Chris --- (6/5)x

x + 2x/5 + 6x/5 = 6
times 5
5x + 2x + 6x = 30
13x = 30
x = 30/13 ft

Sarah --- (2/5)(30/13) = 12/13

(chris has (6/5)(30/13)= 36/13

check: 30/13 +12/13 + 36/13 = 78/13 = 6

2. 1/2 S=2/5 D
S=4/5 D

C=3S=6/5D

S+C+D=6
6/5 D + 4/5 D + D=6
3D=6
D=2
S= 4/5 D=8/5
C=6/5 D=12/5
check, add them up to see if it is aix feet.
