A rectangles length is 2 meters greater than its width if the e perimeter is greater than 112 what is the rectangles possible wi
pishuonlain [190]

Answer:

Step-by-step explanation:

Perimeter of a rectangle = 2(L +W)        

Given L = W + 2      and the perimeter is greater than 112 meters?

  P rect    <   2(L +W)        L = W + 2

  P rect    <   2(W + 2 +W)

                <   2(2W+2)

  112         <     4W + 4        solve for W

(112 - 4)/4  <   (4W +4 - 4)/4              

108/4       <   (4W + 0)/4

       27     <    W              

      the width has to be greater than 27 meters

Convert to a fraction: 150%
BARSIC [14]
So,  all percents can be expressed as *percent*/100
So for this,  it would be 150/100
Then we want to simplify it down and all that jazz.  Find the biggest number that BOTH the numerator AND denominator can be divided by.
In this case,  50.
150/50=3
100/50=2
So now you have 3/2
You might also want a mixed number,  or, a whole number with the leftover fraction after it.
In this case,  see how many times can 2 go into 3 FULLY.
The answer would be 1.  1 is our WHOLE NUMBER.
Then take whatever is left over from 3 and that is our numerator.  Do this,  since 2 can go into 3 ONE time FULLY,  I can say 3-(2*1) is our remainder.
That gives you one as the numerator.  2 is still the denominator.
So a mixed number of 3/2 is 1 1/2
So here is 150% as a fraction:  150/100,  3/2 or 1 1/2.

Which fraction is equivalent to<br> 2/5
My name is Ann [436]

Answer:

To make equivalent fractions, what we have to do is multiplicate or divide the numerator or denominator by the same number.

In our case:

\frac{2}{5}=\frac{2*2}{5*2}=\frac{4}{10}

\frac{2}{5}=\frac{2*6}{5*6}=\frac{12}{30}

\frac{2}{5} = \frac{2*12}{5*12}=\frac{24}{60}

That are only three examples, but there are infinite.

We could also obtain equivalent fractions dividing, for example, \frac{3}{9}:

\frac{3}{9}=\frac{\frac{3}{3}}{\frac{9}{3}} = \frac{1}{3}
