2 feet


2 yards

51 feet

Answer 1

Sophie has 2 yards left.

Answer 2

Alright, lets get started.

Sophie has 5 pieces of string that are 4 yards each.

1 yards = 3 feet,

So, 4 yards =
`4 * 3 =12` feet

Total number of string she has = 5 piece

So, total length she has =
`5*12 = 60` feet

It means she had 60 feet string in starting.

Now, She uses 3 pieces that are each 3 feet long, means

She uses =
`3*3 = 9` feet

So, remaining string length will be =
`60 - 9 = 51` feet

Means 51 feet string does Sophie have. : Answer

Hope it will help :)
