Question

The line plot below shows the lengths of all the pieces of string Emma used for an art project .she cut all these pieces from one original piece of string ?

Answer 1

Answer:

option d) 6 $\frac{1}{8}$

Step-by-step explanation:

In order to find the original length of string adding the leftover piece of string with the pieces of string she cut:

Length= 1 + (1/8) + 4(2/4) + (5/8) + 2(3/4) + (7/8)

           = 1 + (1/8) + (2) + (5/8) + (3/2) + (7/8)

          = 1+2+ (3/2) + (13/8)

          = 3+ (3/2) + (13/8)

          = (24+12+13)/8

          = 49/8

          =6 $\frac{1}{8}$ !

Answer 2

The line plots shows the length of all the pieces used by Emma for an art project, therefore, the original length of the piece is $6\frac{1}{8}$ ft

How to calculate lengths from the line plots?

The line plots gives information on the pieces of string Emma used for his project,  The line plot records the length of the string and the number used.

He has 1 ft leftover after the projects.

Therefore,

length used = $\frac{1}{8} + 4(\frac{2}{4} )+\frac{5}{8} +2(\frac{3}{4} )+\frac{7}{8}$

length used= $\frac{1}{8} + 2+\frac{5}{8} +\frac{3}{2} +\frac{7}{8}$

length used= $\frac{1+16+5+12+7}{8}$

length used = $\frac{41}{8}$

original length = 1 + $\frac{41}{8}$

original length = $\frac{8+41}{8}$

original length = $\frac{49}{8}$

original length=$6\frac{1}{8}$
