Answer 1

Option A is the answer

Step-by-step explanation:

From the question, you were told that a dressmaker has a piece of ribbon that has a total length of Seven-sixteenths.

She cut One-fourth of an inch long from the total pieces of the ribbon.

Given:

• The total pieces of ribbon= seven sixteens inch

• Piece of ribbon cut = One-fourth inch

To find:- Length of raining piece of ribbon = x

Note that the total length of piece of ribbon = remaining length + length of piece cut.

one - fourth = 1/4

seven - sixteenths = 7 × 1/16

→ 7/16

The next thing to find the length of remaining piece of ribbon.

$\frac{7}{16} = x + \frac{1}{4}$

Isolate x by subtracting 1/4 from both sides:

$= > \frac{7}{16} - \frac{1}{4} = x + \frac{1}{4} - \frac{1}{4}$

→ 7/16 - 1/4 = x

→ LCM = 16

→ [(7-(4×1)] / 16 = x

After evaluating, we get:-

x= 3/16 inch

So, the length of remaining piece of ribbon is Three-sixteenths of an inch
