Is 8/5 proportional to 24/15 ?

DiKsa [7]

Hey there!

The answer to your question is, yes, it is

Given:

$\frac{8}{5}$ $and$ $\frac{24}{15}$

To see if they are equal, we can use cross products (see below for information about this, if you don't know what it is). Let us assume they are equal. This would mean that:

$8*15=24*5$

Let's solve it and see if it is true:

$8*15=24*5$

$120=120$

Therefore, they are proportional.

Cross products

WORD DEFINITION:

Given two fractions, you can take the numerator of the first fraction multiplied by the denominator of the second fraction and it should equal the denominator of the first fraction multiplied by the numerator of the second fraction.

ALGEBRAIC DEFINITION:

Given two fractions, $\frac{a}{b}$ $and$ $\frac{c}{d}$ , $a*d$ should equal to $b*c$

Hope it helps, and have a terrificly amazing day!

Find the area of an equilateral triangle (regular 3-gon) with the given measurement.3-inch radius A = sq. in.

Advocard [28]

In its present form, there's not enough information to answer the question.

We'll need to know what you mean by the "radius" of an equilateral triangle,
or for that matter, the 'radius' of any triangle.

Which type of transformation creates a shape where only the angles are congruent to the original shape?

lara31 [8.8K]

Dilations. This is because dilations are a change in size of the shape. However, the angles would stay the same. In the rigid transformations, translations, rotations, and reflections, the size and angles would stay the same.
