1/2 of 4 2/7

= (1/2×4 2/7)

= (1/2×30/7)

= 15/7

= 2 1/7

Answer 2

Answer:

1/2 of 4 2/7 is equal to $2 \frac{1}{7}$

Step-by-step explanation:

Here given,$\frac{1}{2}$of $4 \frac{2}{7}$

We want to find value of this.

So we need to simplify it.

From childhood,we know of means multiplication.

So,

$\frac{1}{2} \: of \: 4 \frac{2}{7} \\ = \frac{1}{2} \: \times \: 4 \frac{2}{7} \\ = \frac{1}{2} \: \times \: \frac{4 \times 7 + 2 }{7} \\ = \frac{1}{2} \times \frac{28 + 2}{7} \\ = \frac{1}{2} \times \frac{30}{7} \\ = 1 \times \frac{15}{7} \\ = \frac{15}{7} \\ = 2 \frac{1}{7}$

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)
