Answer 2

Answer:

25 m is 2.5% if 1 km.

Step-by-step explanation:

Here we want to express 25 metres as a percentage of 1 km.

We need to convert both digit in same unit.

We know,

1 km = 1000 m

According to question,

1000 m means 100%

By Unitary method,

1 m means $\frac{100}{1000} \%$

and 25 meter means $\frac{100}{1000} \times 25 \%= 2.5\%$

So,we can say 25 m is 2.5% of 1000 m

Therefore 25 m is 2.5% if 1 km.

This is a problem of Mathematics.

Some important Mathematics 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)
