Answer:
The equation to find the total yards of lace Fern need is
.
Fern will need 6 yards of lace in total.
Explanation:
Given:
Yard of lace required for each napkins =

Number of napkins needs to put lace = 10
We need to Write an equation to solve this and explain how many yards of lace Fern will need total.
Solution:
Let the total yards of lace Fern need be 'x'.
So we can say that;
total yards of lace Fern need can be calculated by multiplying Yard of lace required for each napkins with Number of napkins needs to put lace .
framing in equation form we get;

Hence the equation to find the total yards of lace Fern need is
.
On solving we get;

Hence Fern will need 6 yards of lace in total.
