Answer 2

Answer:

Number of 11 people are sharing when each has 2/3 of pizza.

Step-by-step explanation:

Given,

There are $\frac{22}{3}$ pizzas.

So total quantity of pizza is $\frac{22}{3}$ part.

Now it is also given that $\frac{2}{3}$ of pizza will get each person.

We want to find number of people who will get $\frac{2}{3}$ of total pizza.

This is a problem of fraction of Algebra.

By Unitary method we can solve this.

$\frac{2}{3}$ part of pizza will get 1 person.

By Unitary method,

1 part of pizza will get

$\frac{1}{ \frac{2}{3} } = \frac{3}{2}$ person.

Now,

$\frac{22}{3}$ part of pizza will get

$\frac{3}{2} \times \frac{22}{3} \\ = 11$

This is a problem of Algebra.

Some important Algebra formulas.

(a + b)² = a² + 2ab + b²

(a − b)² = a² − 2ab − b²

(a + b)³ = a³ + 3a²b + 3ab² + b³

(a - b)³ = a³ - 3a²b + 3ab² - b³

a³ + b³ = (a + b)³ − 3ab(a + b)

a³ - b³ = (a -b)³ + 3ab(a - b)

a² − b² = (a + b)(a − b)

a² + b² = (a + b)² − 2ab

a² + b² = (a − b)² + 2ab

a³ − b³ = (a − b)(a² + ab + b²)

a³ + b³ = (a + b)(a² − ab + b²)
