Question

На пошив наволочки требуется в 3 раза меньше ткани, чем на пошив простыни. Во сколько раз больше ткани пойдёт на 6 простыней, чем на 1 навалочку.

Answer 1

Ответ:

0,7*3=2,1 (м) - ткани уходит на 1 простыню

2*2,1+6*0,7=4,2+4,2=8,4 (м) - ткани ушо на наволочки и простыни

(25,6-8,4):4=17,2:4=4,3 (м) - ткани ушло на 1 полдодеяльник

Answer 2

Calculation of Fabric Required for Pillowcase and Bedsheet

To determine the amount of fabric required for a pillowcase and a bedsheet, we are given that the fabric required for a pillowcase is three times less than the fabric required for a bedsheet.

Let's assume that the fabric required for a pillowcase is represented by P and the fabric required for a bedsheet is represented by B.

According to the given information, we can write the following equation:

P = B/3 ---(Equation 1)

Now, we need to find out how much more fabric will be required for six bedsheets compared to one pillowcase.

Let's assume that the additional fabric required for six bedsheets is represented by A.

We can calculate A by subtracting the fabric required for one pillowcase from the fabric required for six bedsheets:

A = 6B - P ---(Equation 2)

To find the ratio of the additional fabric required for six bedsheets to the fabric required for one pillowcase, we can divide Equation 2 by Equation 1:

A/P = (6B - P) / P

Simplifying the equation further:

A/P = 6B/P - P/P

Since P/P = 1, the equation becomes:

A/P = 6B/P - 1

Now, let's substitute the value of P from Equation 1 into the above equation:

A/P = 6B/(B/3) - 1

Simplifying further:

A/P = 6B * (3/B) - 1

A/P = 18 - 1

A/P = 17

Therefore, the ratio of the additional fabric required for six bedsheets to the fabric required for one pillowcase is 17.

In other words, the fabric required for six bedsheets is 17 times more than the fabric required for one pillowcase.

Please note that the specific amount of fabric required for a pillowcase and a bedsheet may vary depending on the size and design of the bedding. The calculations provided above are based on the given information and assumptions.
