A farmer wishes to fence a rectangular area behind his barn. The barn forms one end of the rectangle and the length of the recta
Semenov [28]
1. The formula for calculate the perimeter of a rectangle, is:

 P=2L+2W

 P is the perimeter of the rectangle (P=320 feet).
 L is the lenght of the rectangle.
 W is the width of the rectangle.
<span>
 2. The problem says that the length of the rectangle is three times the width, so you have:
</span>
 L=3W

 3. When you substitute L=3W and P=320, into P=2L+2W, you obtain:

 P=2L+2W
 320=2(3W)+2W
 320=6W+2W
 8W=320
 W=320/8
 W=40 feet

 4. The barn forms one end of the rectangle. Therefore the linear feet of fence (x) is:

 x=P-W
 x=320 feet-40 feet
 x=280 feet
<span>
 How many linear feet of fence must he buy?
</span>
 The answer is: 280 feet

What's three equivalent ratios for 6/9
vaieri [72.5K]

Answer:

Three equivalents ratios for 6/9 could be 2/3, 12/18 and 18/27

Step-by-step explanation:

An equivalent ratio refers to the same number but written differently. For example, for the ratio 6/9, we could obtain the following equivalent ratios.

First equivalent ratio

You can divide the numerator and denominator by 3. You get 2/3

\frac{6\div 3}{9\div 3}=\frac{2}{3}

Second equivalent ratio

You can multiply the numerator and denominator by 2. You get 12/18

\frac{6\times 2}{9\times 2}=\frac{12}{18}

Third equivalent ratio

You can multiply the numerator and denominator by 3. You get 18/27

\frac{6\times 3}{9\times 3}=\frac{18}{27}

Thus, three equivalents ratios for 6/9 could be 2/3, 12/18 and 18/27
