Question

2/8 of a rope is 28 meters.What is the length of the rope? A.32 B.42 C.4 D.21​

Answer 1

let length be x

ATQ

$\\ \sf\longmapsto \dfrac{2}{8}\times x=28$

$\\ \sf\longmapsto \dfrac{2x}{8}=28$

$\\ \sf\longmapsto \dfrac{x}{4}=28$

$\\ \sf\longmapsto x=4(28)$

$\\ \sf\longmapsto x=112$

Answer 2

Step-by-step explanation:

there is something wrong with your problem description.

the offered answer options do not fit to the solution as it is described.

2/8th of a rope is 28 meters long. how long is the whole rope ?

as the other answer said : 2/8 = 1/4

and 1/4th of the rope x = 28 m

1/4 × x = 28

x (the length of the whole rope) = 4×28 = 112 meters

but - maybe the original problem said that 7/8th (and not 2/8th) of a rope is 28 m.

7/8 × x = 28

1/8 × x = 4

x = 32 m

then A (32) would be the right answer !
