explain why multiplying the numerator and denominator of a fraction by the same number results in an equivalent fraction

Tomtit [17]

Think: You're treating the numerator and the denom. in precisely the same way. In doing so you are NOT changing the value of the fraction, only the appearance.

Example: start with 2/3. Mult num. and den. both by 7: 14/21.

2/3 and 14/21 result in precisely the same decimal fraction, showing that the latter set of fractions is equivalent to the former set.

The area of a rectangle is 24396

Oksanka [162]

Answer: Length = 642 cm

Concept:

Here, we need to know the idea of how to find the area of a rectangle.

Area (rectangle) = l × w

l = length

w = width

Solve:

Given information

A = 24396 cm²

w = 38 cm

Given expression

A = l × w

Substitute values into the expression

24396 = l × (38)

Divide both sides by 38

24396 / 38 = l × 38 / 38

$\boxed{l=642}$

Hope this helps!! :)
