Answer:

Number of groups formed by '<em>p</em>' people = \frac{p}{4}

Number of groups formed with 28 people = 7

Step-by-step explanation:

We are given that, there are 4 people in 1 group.

Now, at first we have to find the number of groups formed by '<em>p'</em><em> </em>people.

Here, we will use the unitary method.

Number of group formed with 4 people = 1

So, number of group formed with 1 person = \frac{1}{4}

∴ number of groups formed with '<em>p'</em> people = \frac{1}{4}\times\;p=\frac{p}{4}

So, the required expression for the number of groups formed by '<em>p</em>' people is \frac{p}{4}

Now, secondly we have to find the number of groups formed by 28 people.

As, we know that number of groups formed with '<em>p</em>' people = \frac{p}{4}

Now, putting '<em>p'</em> = 28 in the expression obtained above, we get

number of groups formed by 28 people = \frac{28}{4} =7

So, there are 7 groups formed with 28 people.

First, rewrite 14/25 and 11/20 so that they have a common denominator. Then, use &lt;, =, &gt;
muminat

Answer: 14/25 = 56/100

               11/20 =  55/100

               14/25 > 11/20

Step-by-step explanation:

The least common multiple of 20 and 25 is 100.

(100 = 20*5, 25*4)

So we can take the common denominator 100.

14*4/25*4 =56/100. ∴14/25 = 56/100

11*5/20*5  =55/100. ∴11/20  = 55/100

56>55

∴56/100 > 55/100

∴14/25 > 11/20

Hope it's good;)
