Answer:
The length of the curtain, after adding the new length is 2 ¹/₂₄ yard long.
Step-by-step explanation:
Given;
initial length of the curtain, L₀ = 1 ¾ yard = ⁷/₄ yard
length of the lace Jan will cut from, L = ⅞ yard
fraction to be cut from the yard, x = ⅓
New length to be added is given by;
[tex]L_{new} = \frac{1}{3} *\frac{7}{8} = \frac{7}{24} \ yard[/tex]
Total length of the curtain, after adding the new length is given by;
[tex]L_{total} = L_o + L_{new}\\\\L_{total} = \frac{7}{4} + \frac{7}{24} = \frac{42+ 7}{24} = \frac{49}{24} = 2\frac{1}{24}\ yard \ long[/tex]
Therefore, the length of the curtain, after adding the new length is 2 ¹/₂₄ yard long.
