Question

The fraction 7/8 is really close to 1, so Yvonne could estimate that she needs approximately yards of fabric per dress. So, to make 5 dresses she would need approximately yards of fabric

Answer 1

Given Data:

The total yard of fabric for one dress is: y=1

The total dresses Yvonne expecting to make is: n=5

The expression to calculate the total yards requered for 5 dresses is,

`\begin{gathered} n* y=5*1 \\ =5\text{ yards} \end{gathered}`

Thus, Yvonne needs 5 yards of estimated fabric to make 5 dress.

The expression to calculate the actual amoud of fabric is,

`\begin{gathered} 5*(7)/(8)=(35)/(8) \\ =4.375\text{ yards.} \end{gathered}`

Thus, the actual length of fabric should be 4.375 yards.
