Question

Susan' rope is three times as long as Fred's rope. Fred's rope is twice as long as Alison's rope. The total length of all three ropes is 36 meters. How long is Fred's rope?

Answer 1

S = 2F; F = 2A
S + F + A =36

Answer 2

F = 2A and S = 2F => S = 4A

Answer 3

Don't understand

Answer 4

S = 4A, F = 2A
4A + 2A + A = 36

Answer 5

Okay so let S be the length of sally's rope

Answer 6

F - fred's A - alison's

Answer 7

okay

Answer 8

Woops meant not S = 2F, its S = 3F (Three times as long as fred's)

Answer 9

S = 3F
F = 2A
A
S + F + A = 36 (total length)

Answer 10

S = 3F, but F = 2A => S = 3*2A = 6A

Answer 11

So you have:
S = 6A
F = 2A
A = A (A is just A)
S + F + A = 36
6A + 2A + A = 36

Answer 12

9A = 36 = > A = 4

Answer 13

F = 2A = 2*4 = 8 meters => Fred's rope is 8 meters long, please click on become a fan if I helped, thanks!
